Ultimately, SRX expanded Fantom-X will have a much better, more exciting, characterful soundset than dull, bland and generic "best of SRX" joke that is Fan-G ... (It's not bad, just not as good ... )
I tested Fan-G and Fan-X side by side and found precious little sonic difference between the two ... Only new Fan-G patches sounded different and mostly because of programming probably ... In fact, the big difference is a boomy quality to Fan-G's low end ...
I already had a beloved Fan-X when G came out and was never impressed enough to get G ... There are improvements, alot of them actually, but there is a lot of smal backward steps, too ... And ultimately, the soundset I already have on X is better than what's available on G ... And in the end, that's what's most important along with the fact they did not change keyboard action on synth models and USB transfer speed wasn't improved enough ...
I don't think the Fan-G is any worse than M3 or XS ... It's a very good board ... But when you want to upgrade and can't justify, something's off ...
I'd say go for Fan-X if you can find one at a sweet price ... Later, when you get to know the very good internal soundset, you can figure out where you want the sounds beefed up ...
When it comes to functionality, there's actually not that much that Fan-G can do over X ... and there's actually many thing X does better than G, for starters, the arp for example ... Very flexible on X ... On G, you can't even create user patterns (facepalm) ...
If you have more questions ust ask ...
