MiG-29OVT versus the Su-37 which is one is the best

The MiG-29 is used by 30 Countries and 1600 have been produced; around 900 Su-27s have been produced and it is used by 16 nations.

The MiG-29 is picking orders from Yemen, and a classified middle eastern Country India operates both types is the MiG-29OVT the top end of Russian fourth generation aircraft?

I have seen the video of the MiG-29OVT in MAKS 2005 an expectacular bird.
