They are just two very different approaches... I thought the activation of Segwit will then followed by "easier/better" future plan of blocksize increase?
Perhaps we can compromise and buy time by allowing bigger blocks (eg. 2MB) to activate, and then decide if Segwit should be implemented?
Segwit IS the compromise, and it's more of a compromise towards big blocks than what you're suggesting.

Which is bigger, 2 MB blocks or 4 MB blocks
