Beyblade Burst

Both are same. Spinners and monster/spirit inside them that makes them more powerful than ordinary spinner. 

Most people have only watched the original beyblade. Burst is the newest one with a different plot m characters, and toy line. You will enjoy this if you liked the plot of the original. They are interesting just like metal series. 

They are both sports anime with younger main characters and both anime are really similar. 

Both anime are about colorful characters battling it out with Beyblade/Shadowverse. Most of the voice actours are the same exact people too. Both are really fun anime, and it's nice that you can do the very same stuff they do in the anime irl. 

Duels with toys that actually have great power and influence on the reality in these universes, making for more large scale conflicts. The toys being spinning tops.  

It's based on a Toy Competition, with a cast of colorful characters.  

Both more recent iterations of super popular kids anime franchises (beyblade & yugioh). Both have very similar appeal & art styles. Both with impeccable character designs, a standard set for their larger franchises as a whole.
