It takes about the same time (maybe an extra 5 mins) to get going but it uses more charcoal.

It's also about 300lbs and is over $1200 (you can sometimes find them second hand though).

The big advantage with the BGE is heat stability from all the ceramic thermal mass. This is awesome for smoking & slow cooking but is of little benefit when grilling steaks.

I love them both but for different reasons.

The advantage of the go anywhere is it's so cheap & portable. If you end up loving cooking with charcoal, you can then splurge on a BGE. If you hate it then you're only down $80.
