What's difference between dragoons?

I went onto beybladepremier, and I searched dragoon. Found the b 181 03 and it's in my price range. How good is this beyblade?  Also not too sure what the difference is between b-194 07 dragoon v2, or b-156 02 dragoon victory?

Still very new and I'm trying to learn the terms. Are burst rise gt, burst dynamite the sets/series they come from? And are they compatible with other sets? 

Ive also been reading up and I saw the pro series set is pretty good to start off with as a beginner?

Sorry for all the questions! Just browsing beyblades and planning future buys!

Edit: changed title cause I didn't wanna break any rules
