Which is better for virtualization?

The Supermicro, because two sockets and up to 2TB of RAM let you pack far more VMs per board. The Gigabyte's 64GB listed memory ceiling limits VM density.

Which has faster storage and networking?

The Gigabyte. It has PCIe 4.0 and dual 10GbE on board, plus an M.2 slot. The Supermicro listing shows PCIe 3.0 and no on-board 10GbE.

Is the Gigabyte worth the extra?

There is no Supermicro price given here, so check its live listings first. If the Supermicro costs more, you are paying for a second socket and much larger memory capacity.

Can I use EPYC 7001 chips in both?

Only in the Supermicro, which lists EPYC 7001 and 7002 support. The Gigabyte is listed for EPYC 7002 (Rome) only.

Which supports more memory?

The Supermicro, at up to 2TB of registered ECC DDR4 across 16 slots. The Gigabyte spec lists 64GB of RDIMM, a much lower ceiling.

Do either have integrated graphics?

Both listings say integrated graphics yes, but these are server boards with basic BMC video, not gaming or workstation GPUs.
