Pulling my hair out. What phablet to pick?

Hey all, I'm torn between a Huawei Mediapad X2 or a Huawei Mediapad M2 (or m2 lite?)

I'm looking to upgrade from a Samsung Galaxy S2.

I'm more inclinded to the X2 or wait for X3, just because of the pixel count 323ppi compared to the 283ppi on the M2.

Been reading on here that people upgraded from the X2 to the M2 because of the speakers?

Does the x2 have 6.0 android now?

I really like the idea of a phablet. What would you choose. I like to watch YouTube and Twitch. But also like to take decent pictures. Any ideas? Also like big screen phones.

Thank you guys :)
