I like both.
I've got an R33 GTS-t and a '93 NA Aero Top Supra.
Skyline is more fun. NA Supra is nice to cruise, but with auto box that's about it.
I was amazed by how fast the TT Supras are with only exhaust and pod filter. My friend bought one and ever since driving that my skyline feels so slow.
Now my Supra's up for sale and Skylines in for some mods in the near future..
