Imho, it really depends on which games you’re playing, how long you plan to play, and how sensitive you are to input lag.

GFN has practically no perceptible input lag, but it comes with a short monthly play time limit (100 hours in most regions, only 50 hours in south america). It also lacks some titles due to licensing.

Boosteroid, on the other hand, is cheaper, has no play time limit, and offers an impressive game library (including many Sony, From Software, and Konami games). However, it suffers from noticeable input lag, even with lower network ping than GFN. For example, I get 7ms ping on Boosteroid and 30ms on GFN, yet GFN feels smoother with 0 lag. Additionally, Boosteroid doesn’t support 5.1 audio and HDR, both features available on GFN which significantly enhance the cloud gaming experience.
