I have the GE250. To be honest I think it's great. My bug bear was the lack of bass support. I've only had the POD for one day but it's really growing on me. I love the stomp mode, I could just use this in a live situation and be done.
I feel there more of a deep dive on the POD to craft your tone. So many settings and easy to use. Plus the community is brilliant, there's so much out there to pick up with presets and Irs.
The expression pedal is definitely better with the POD too.
The Mooer feels a little more powerful in terms of; no gap in sound when selecting patches and whilst all but 2 of the fx slots are pre filled, you can have everything you need for a tone. (So delay, reverb, amp, cab, OD/Dist, EQ, Gate are in every tone then you can add 2 more)
It's possible to get great tones out of either but for functionality and community I'm leaning to the POD.
