Hello TP-Link Community,

I'm about to purchase a 5G Deco system for long-term use (8-10 years) and need updated advice on choosing between Deco X50-5G and Deco X3000-5G.

I found this thread from June 2024: https://community.tp-link.com/en/home/forum/topic/671632 where @David-TP recommended the X50-5G as the main model.

However, we are now in October 2025.

My questions:

1. Is the recommendation still the same (X50-5G), or has something changed?
2. Which model will receive firmware support longer - the X50-5G or the X3000-5G?
3. Are there any known stability issues with the X3000-5G I should be aware of?

Use case: Primary internet via fiber box connected to WAN port of the X50-5G or the X3000-5G, with 5G as automatic backup failover in case of fiber outage. Location: France. 

Thank you for any updated guidance from @David-TP or experienced users!
