BE86U worse wifi latency vs old ax86s

Hey,
I previously had an ax86s as a solo router but was looking to improve coverage soo I ended up getting a BE86U. I set up the be86u as main router and the old ax86s as an aimesh node.

The setup has been working stable without any issues, however I noticed wifi latency on the BE86U was a good 1-2ms higher just by running speed tests on multiples devices.

Soo I decided to run pings directly to the router while on 5ghz wifi (ax201 client)
Average ~2ms max 10ms after 100 pings.
I then forced the client to the node (ax86s 192.168.50.66) and did the same test
Average 1ms, max 6ms.

I have a pretty simple network setup with no vlans and a single ssid.
I've tried disabling wifi7 and messing with professional settings but no change, BE86U noticeably higher latency. Same goes for phones and a wifi7 laptop I have. Speeds are about the same between the two considering distance, etc

Edit:
Disabling MU-MIMO is the only thing that seems to help.
TX power is also very low when set to CH36. wifiman reports 14dbm, while ax86s is at 18dbm.
2.4ghz ~14db, 5ghz ch100 ~23dbm both models. EU models (E0/DE)

How bad would it be to change Region to US to get about the same TX power on both models on ch36? I'd lower 2.4ghz tx power to meet EU regulation, last thing i'd want is to have 2.4ghz blasting at 30dbm...
Ideal solution would be for asus to fix their firmware. Doesn't make sense be86u having lower TX power when set to ch36-64, especially when both ax86s and be86u are EU models.
It would also be nice to be able to manually adjust TX/channel for each node for roaming purposes. Like lower 2.4ghz to avoid overlap/interference and 5ghz bit higher soo it's always preferred.

Any ideas on whWhat firmware and version are you running? 3.0.0.6.102_39260 is the latest Asus version which has some fixes.
What firmware and version are you running?

I was on latest asus. Now i'm on latest merlin.
Disabling mu mimo helped a lot, seems more normal now, still higher/less stable compared to ax86s

Also, tx power is different when set to ch36 despite both having same region. (wifiman reports 14dbm for be86u and 18dbm for ax86s)
