With SegWit being a totally plausible solution (a temporary solution, mind you), I think sticking with core will be the best.
If only the Core devs implemented SegWit and a blocksize increase together...

SegWit seems interesting, although we'd better judge it when complete. I think it's important that it's a soft fork though, block size increase isn't.
