Phone or portable router, or a modem on Snapdragon X55?

Hey, colleagues!

Please, recommend a phone or portable router, or a modem (M.2 form factors) to install in an existing router. From what I’ve read earlier, I understand that the flagship in terms of value for money is now the Snapdragon X55. What’s your opinion?

I would like to have aggregation, 4x4 MIMO, the ability to connect external antennas, which is hard to achieve with a mobile phone. But in case of a better chipset, for a comparable price, I would choose a Qualcomm phone.

Budget under 350 EUR. I’m looking at Xiaomi MI 11 Lite NE 5G, it’s on Qualcomm Snapdragon 778G. RF System Snapdragon X53 5G Modem.

NETGEAR AC810 I have now. Of the portable routers on the market:
LTE | NETGEAR AC810 | 3CA, 2×2 MIMO | Qualcomm Snapdragon X12 | Pre-Owned 140-240 EUR
LTE | NETGEAR MR1100 | 4CA, 4x4 MIMO | Qualcomm Snapdragon X16 | Pre-Owned 240-280 EUR
LTE | NETGEAR MR2100 | 5CA, 4x4 MIMO | Qualcomm Snapdragon X24 | Pre-Owned 350-380 EUR, New 560 EUR
5G | NETGEAR MR5200 | 6CA (?), 4x4 MIMO | Qualcomm Snapdragon X55 | Pre-Owned 680 EUR, New 1100 EUR
5G | ZTE MU5001 | 5CA (LTE), 4x4 MIMO | Qualcomm Snapdragon X55 | New 300-350 EUR
5G | ThinkPad SDX55 5G sub6 M.2 WWAN Module | ?CA, 4x4 MIMO | Qualcomm Snapdragon X55 | New 350 EUR

The prices of the used devices are taken from Ebay.

It turns out that for a price under 350 EUR you can get, a Xiaomi MI 11 Lite NE 5G phone with X53 or a router from ZTE MU5001 with X55. Are there better options?
