Whatever synth you choose, it's gotta be right for YOU.
Whether it's Korg, Roland, Yam, whatever. Like you said in your opening thread, you want something that's easy to operate. As for the fat sounds, that's best achieved after tweaking parameters, to attain the sound YOU want. Some people are happy with Korg (like me), other's...Roland fits the bill. It's all a matter of preference.
Good Luck in your search.
