Seeker 3 or 3.5? Upgrade to a Cinelog 25?

I have a cinelog 25 and its a great quad, but I'm flying in larger fields and would rather have something a bit more freestyle-y and fun.

I like the idea of the seeker 3, as I'd be able to use all my 850mah 4s lipos that I have for the cinelog on it.

My only concern is that spending loads of money on it, and it wouldn't feel massively different from the cinelog 25? Has anyone flown similar and can give their opinions?

The seeker 35 would definitely be puncher, but would require buying a load of 6s batteries to run at its full potential. Has anyone flown it on 4s?

All opinions welcomed, as im really struggling to make any decisions!

Thanks
