I was on Omada, before moving off to another platform.
Pros and cons, I think. Omada is cheaper than Unifi - it's TP-link's attempt to enter the same space, and they've been trying a long time.
My main reason for moving out of the platform is a lack of long-term support. I feel TP-Link brings its consumer buying ethos to the Omada platform, which is supposedly targeted at the enterprise market. What do I mean by that? Software support is okay, for the first year and as long as the product remains "current". The moment they release new revisions or updated hardware, they immediately obsolete the older hardware without support (a no-no when enterprises would reasonably expect at least 5y of software support - security and bug fixes in firmware updates is particularly important).
Held my 3x EAP245 v1 for over a year without software support, even as the v3 gained plenty of updates in that time. Also, their controller update broke features they never intended to fix even after writing in to them, and they confirmed they EOL'd a product barely 2y after launch, recommending me to buy their v3 if I wanted support, which was very disappointing. Even Unifi does not play these software support games - they cannot afford to in the enterprise space. The tech refresh cycle for networking hardware isn't 2-3y in this target environment, unlike what TP-link seemed to imply in their reply to me. Home users can afford to replace hardware often, but even so typically do not change it every 2-3y also, what more something that's targeted in the office space that's usually deployed for 5y or longer.
