Alright then, gonna yse the same format as you I guess.
For the original
Bakuten Shoot Beyblades we have:
Trypio - Being a huge Maximum Garuda lover, I couldn't not include this. While I don't love this as much, the idea is really cool even though it performs like carp. It's really fun to use and just see what the big AR can do. It is a very unique beyblade too.
Spike Lizard - As someone who loves roller gimmicks, this one is no exception. I love the way it all looks. Even though it's performance sucks, it's beautiful aesthetically and I like the amount of rollers placed on it.
Makendo - Well, you've explained it already.
Bump King - You've explained that too.
Spark Knight - I'm talking about the Takara one and only Spark Knight. What Spark Knight has over Polta and Saizo in my opinion is the colours, that translucent amber is lovely! I was also always a fan of compact beyblades too.
Draciel F - I know the F series isn't liked that much, but Draciel F stands out for me. I like that the AR actually feels like a defense type AR, it feels more closed off. The BB is pretty cool, I love rolling ball gimmicks. Not sure if this one counts because I'm unsure how popular this one is but I always thought people didn't like this one.
Galeon 2 (with Black EG) - I'm cheating a little bit here but this applies to stock Galeon 2 as well. Even though it sucks there's no longer an S-AR making this a bit blander, I love the crazy design of it so much! It looks like recoil-y fun,
and the anime made me love it more for some odd reason. I think I'd love it way more with a black EG, so it can be show accurate. Both of those combined has made what I considered my most wanted beyblade ever.
For
HMS we have:
Draciel MS - You've explained why. Recoil is the best!
Round Shell MS - Now I'm not sure if this one truly is unpopular or not, I do find that it does get overlooked upon. I hardly see videos with this one, not counting collection videos. I think this is one of my favourite HMS beyblades, but I've always had a thing for round compact thick defensive beyblades, and in green no less. While it is kinda weak in opposite spin battles, in same spin battles, this thing can be a beast, destabilizing Wolborg MS so well, hell I've gotten it to do the same to Earth Aquila almost consistently. I really don't care for it's Beywheelz gimmick though, but it's still a fun feature I guess.
Now for the
Metal Fight Beyblades:
Dark Bull H145SD - The colour scheme looks really really good, it all just works together, even though they are all similar colours. H145 is useless but it's really fun to use, and on a stationary tip like SD, it's recoil-y fun.
Clay Aries ED145B - Now I love Rock Aries, but I love this just a bit more. I always found Light wheels, as horrible as they perform very interesting, and I love the idea of having something generic bladers used in the anime. I always loved the way Clay looked. This beyblade is more for looks more than anything but I still like it. I really love the anime appearance too.
Storm Capricorn M145Q - You've explained this one too.
Killer Gemios DF145FS - You've explained why, and I just think it's a beautiful beyblade, I just wish TT put a bit more effort into giving it newer parts.
Thermal Lacerta WA130HF - People hate this one because it's a useless and badly performing beyblade, and the colour scheme. I'll agree that it's performance sucks and it's useless but at the same time the ridiculous pairing of HF and Thermal is pretty fun in my opinion, and the way it looks is good enough for me, I kinda like the colour scheme.
Forbidden Eonis ED145FB - I really really love the appearance of this beyblade, it has this nice clean and light pinkish red colour, the translucent purple ED145, the nice pearl red, oh it just ties in well together. This thing performs badly, but I always loved a lot of light recoily beyblades. The anime appearance of it is cool too.
Finally, for Beyblades
Burst:
Trident .H.C - Already explained.
Storm Spriggan .K.U - Already explained, and also love the way it looks.
Kreis Satan .2G.Lp - Reasons already explained, plus it's one of my absolute favourite beyblades in Burst.
Jail Jormangand .I.Cy - While I don't love this beyblade as much as I used to, it's still a decent beyblade for me. It doesn't perform that well but I like the whole gimmick with Cycle and J2 in this booster form looks amazing, way better than the RLC counterpart.
Quad Quetzalcoatl .J.P - A lot of people dislike this beyblades for the same reason as they dislike Thermal Lacerta, useless, bad combo and ugly. I personally think the looks are really nice, the layer looks unique and cool, and the colour scheme while weird does appeal to me. The Jerk disk is unique for it's time, even if it's useless and Press looks great in that colour. It's pretty cool in the show too, it's probably one of my favourite Dual Layers.
Edit: I forgot Quad Quetzalcoatl.

No I don't plan on doing more yet.
I should probably go back to making fan custom Zero G beyblade concepts again
