I already had a GBA Everdrive but I picked a GB/C one up because for about a year after release, the FPGA cores didn't support the display emulation features of the Pocket, which is a good chunk of the reason I bought mine. I believe they are now all fully supported though. The Pocket's sleep doesn't really work with flash carts either, so arguably the core + SD card route is now the better option, though I still own my AGS-101 model SP and GB micro, and it's cool to play on those still sometimes.
