Synthetic ATF?

[Cerwin Vega Fan]

I noticed the local auto parts store sells things like Mobile 1 synthetic ATF and B&M Trickshift fluid. I was wondering would this stuff be worth the switch? I have a new tranny pan on the way and of course I will have to change my fluid when I get it so I was looking to make an upgrade. Is synthetic ATF worth the extra money?

Thanks

I ONLY use Mobil 1 syn for oil and ATF
