In general I like the upcoming NetMetal ax and L23UGSR-5HaxD2HaxD, as an alternative in Mikrotik's "custom LTE router" lineup...
But some feedback based on specs...
1. Any reason it does not support USB 3.0? This kinda limits it for use with high-speed LTE networks because of the USB bus speed with USB 2.0 (since CPU looks like it can handle CAT18+). And the LtAP, wAPacR, M33 all support USB 3.0 via miniPCIe, while these newer AX model don't. Perhaps the SoC doesn't have USB3 controller, dunno. But USB 2.0 is limiting (and annoying since often modem modules like Sierra/Telit come in USB 3.0 mode, so have to be switched before use)
2. Surprised it doesn't have an M.2 slot since that's what's need for most 5G modem modules these days. There just not a lot of newer LTE/5G modems in miniPCIe FF.
3. Voltage specs is <30 volts, so yet another model without 48V PoE. Dealing with all the different PoE specs is PITA, and since can't often mix 24V passive for uplink with 48V 802.11at APs on same switch (certainly not in Mikrotik's switch products, and mixed voltage switches rare elsewhere too).
4. A 2nd SIM slot like LtAP would have been nice. Or some eUICC/eSIM hardware on board be even better...
Summary: In my LTE use cases, we use wAPacR (with 16M flash) today, so IPQ-5010 on these models still be an upgrade... but just that it's annoying replacing those we lose 48V and USB 3.0, but get more flash, better processor, and AX. (And current LtAP and RBM33 for LTE are MIPS, so no BTH/ZT/container/etc, unlike the ARM).
