G70 and E80 styles are often similar, but tweaked for their respective soundsets, but the E80 DOES have some extra ones (and there were more released for OS2). Personally, given a choice, I might go with the E80's styles, given that its' soundset is newer than the G70's, and I think it has ALL the G70's styles as well as its' own (as well as an Insert FX for a style Part)

The new OS allows you to edit your styles in the GW-8 itself. From past experience, you can expect a fair percentage of G70/E80 styles to work fairly well without tweaking much, but some will take a bit of work.

They should at least load and play without any further work, but sounds vary a fair bit (and there is an insert MFX section to add to a style part, which isn't on the G70, and may not translate from the E80 without knowing which Part it is applied to, and what FX it is).

You also have fewer fills (four to the G/E's six) but they appear to map OK. Overall, you should expect to do at least SOME work to get them to sound their best, as different from the E's soundset as the GW is. But probably no more than any other arranger. Try getting a T2 style to work in an S900 without at least SOME work!

I think you will be pleasantly surprised.

When you get your GW-8, make sure it has the latest OS and styles. You can't edit the styles until you do...
