Can I chime in and say that I hate both of them?
Trying to argue that the Abaranger mech is too simplistic against the Kyoryu stuff is one of the greatest examples of pot calling the kettle black.

In what way exactly? The battery gimmick at the very least makes the Kyoryu stuff more complex. Abaranger mechs just attach, at least the legs and arms get out of the way for the Kyoryuger mecha.

Simplistic? As Den-O Said for the Aba stuff all you did was attach them, that was about it. The Kyoryuger stuff you have to attach the beast battery, open stuff, move stuff, stuff happens.

To elaborate on what I think I was trying to say before:

The Abaranger mech have really strong dino forms but very weak arm modes. The Kyoryuger mech, however, have strong arm modes but lack a good dino mode, if only because they're all remolds of 1 of the 2 arm types.

Maybe when the 4th dino sentai comes along they'll have both a good dino and limb mode. :lol

I really don't feel that sliding the legs around makes the Kyoryu toys that much more complicated.
Being marginally more complex does not a stronger toy make.

Also, like I said, I hate both of them. I was just playing devil's advocate :lol

The Bakuryu look better than the Jyudenryu. But Kyoryujin looks better than AbarenOh. So they're about tied really.
And for what it's worth, scissor tails are pretty cool.

Green Parasaur? Somewhere a Shoji x Ian shippers is happy...
