which one is the best neo geo emulator

after browsing the front page in the neo geo section, i found that

there are at least 4 kinds of neogeo/neogeo cd emulators

its more confusing cuz the cd type and the catridge type isnt separated

out of neogeo and neogeo cd which would you say is better

and of the console type which emulator would you say is the best

As of now Neogeo CD is fully compatible with sound, speed, and games. The downside is the Neogeo CD roms are just too large.

The regular NeoGeo runs quite fast and smooth but CONS: some of the larger games are not supported yet or don't run too well due to memory limitations. PROS: the rom sizes are much smaller than neogeo

I just use the Neogeo CD "roms" without the mp3's, makes them a more reasonable size.
