AM5 Motherboards - best long term support?

[GoogalyMoogaly]

So I'm hoping to get an AM5 motherboard soon for a new X3D CPU.
I don't know which one I want to get. I don't know if I should go X670 or B650.
Most of my motherboards in the past have been Asus, so I was thinking of going down that route and probably picking up a Strix board of some kind.
But then I got to thinking, if my hope is to keep the motherboard for a while and make use of the hopeful longevity of the AM5 socket maybe there are some thing I need to consider first. Maybe I need to look at PCIe 5.0 and get as many of those slots/NVMe connectors as possible, maybe I should be looking to get USB4. But I guess another important factor is, will the board get the required BIOS updates to support the new CPUs (e.g. 8000 series, 9000 series, etc.)?
So since I've only really had Asus boards in the past and have mostly gone Intel where it's often been 1 and done as far as CPU generations go, I was wondering is Asus a good brand to go for? Will they get the required BIOS updates to support the new chip and support them well? Is there another brand that historically has been better for releasing BIOSes to support the new AMD CPUs?

Are there any "killer" motherboards this time around I should consider before I just go and buy an Asus Strix board?

If you do a search for say... the lowest-end motherboards available, which would be A320, all the big brands have a bios update available for Zen 3. I can't say how stable those updates are, but I wouldn't buy MSI over Asus, for example, just because of the compatibility situation.

Based on the previous support tables that AMD have announced, they are inclined to make support exclusive to chipset, but after the push back they got, none of these restrictions have been carried forward and the entire range have all the updates.

USB4 I think I'd only care about if you're likely to use devices that need it. For the average gaming system, I suspect that's not very often. With flash and external drives, my experience is that their transfer rates are so poor/inconsistent they can't even saturate USB 2 properly, let alone USB 4 (but maybe that's because I use freebies / buy junk )

With PCI-E 5.0, it is hard to speculate for the future, but, I really don't think (based on current PCI-E scaling articles) that it is going to matter before the system is dead. Ironically, it is more likely to matter for low-end systems, with low-end cards, which are less likely to be PCI-E 5.0 compatible, than for high-end systems with high-end cards. With AM5, you get 1 PCI-E 5.0 M.2 with B650, even if the graphics card slot is PCI-E 4.0, so I wouldn't worry about that one.

There's also that, if you go all-out for the goodies and get a high-end board with X670, PCI-E 5.0 graphics, PCI-E 5.0 M.2, USB4 on the rear I/O, then you could have got 2 perfectly capable B650 boards, which for me makes it pointless.

Asus is a very good company but tends to be a bit more expensive so you will hear the Asus tax mentioned a lot. I don’t think you could go wrong getting a strix at either x670e or b650e. AM5 will be getting two more chips at least with Zen 5 and Zen 5 X3D so getting a board with some headroom for upgrades won’t be bad either.
