a review seriously complains about b550m aorus elite, despite it is on sales at ~$86usd from msrp $109usd on china.
gigabyte b550m aorus elite
vcore vrm 5*1H+2L
however, there are 5 low side mosfets on the back pcb without any heatsink, same thing what gigabyte did on x570 gamingx.
1*usb 9pin internal header only, instead of 2 on b450m elite.
any gpu thicker than 2 slots will take some space over the bottom pcie x16 slot, namely this mobo support no other pcie device/card when >2 slots gpu is installed.
good thing is then supporting 22110 m.2 and that m.2 avoids hot exhaust air from gpu and no height limitation of m.2 heatsink.
the second m.2 slot is pcie3.0x2 only instead of x4, same as b450m elite.
but it should still be faster because of the pcie3.0x4 between b550 chipset and cpu, rather than pcie2.0x4 between b450 chipset and cpu.
3 fan headers only instead of 4 on b450m elite.
poor sata headers placement just like b450m gaming, worse than b450m elite.
have to use L shape sata header cable for headers under 2 slots gpu.
sadly there is only 1 L shape sata header cable included in the box, another included one is with both side vertical headers.
wired bios flashback button location on the pcb rather than on the i/o side.
vrm temp of the back low side mosfets,
118c and black screen eventually @ 3900x 1.4v 4.4ghz fpu ;
109c @ 3800x 1.4v 4.4ghz fpu 145w ;
105c for stock 3900x @ 3.95ghz only.
(room temp 25c, aio cooling, open test bench)
=>140w seems to be the max "safe" level before black screen/reboot/drop frequency on this mobo.

what cpu are you going to use
