This is an old thread, but just to revive it, it is silly to talk about Philippines as a country when there are huge differences depending on where you live. No different than Thailand - one person's heaven is another's hell. For example, we were in the process of relocating to Bonifacio Global City (BGC) in Metro Manila before getting stuck in Bangkok due to Covid. In many ways, BGC is nicer and more modern than anywhere in Thailand. We currently live in Bangkok and BGC has more green space, is more walkable and has cleaner air. many other areas of the Philippines (including most of Manila) are truly awful though, so if that is what you have seen I can understand the perspective. But before judging the Philippines (and especially Manila), spend some time in BGC.
I saw a mention of Cebu as a location and that is one I would personally avoid -- for the very reason another poster said it was a good option! Specifically, it is loaded with very old white guys holding hands with teenage girls. I find this embarrassing and don't want to be put in this group (my wife is a Filipina, but not a child). Cebu is cheaper than Manila, but I personally prefer Davao by far. Nicer people, less crime, less old white guys, more relaxed but still plenty to keep you occupied.
BTW, in general most things throughout thailand are superior (infrastructure, supermarkets, food, transport, etc.). However, Philippines has one HUGE advantage - the people. You can be welcomed there and make genuine friend, unlike in Thailand where you are always a foreigner and never truly belong.
Bottom line, for 90% of people Thailand is still a better choice, but depending on your circumstances (and budget -- BGC is not cheap!), the Philippines can also be a viable option.
