Alternatively, Binance or ByBit P2P has a PayPal option I think? Just make sure to transact with people with a really high reputation so you won't lose your money due to chargebacks.
I think it highly depends on your location also. There are probably a number of countries where crypto direct deposits on their PayPal accounts are still not allowed. I'm not a hundred percent sure but even in countries where cryptocurrencies are already supported, there might still be users who are ineligible for such feature. Somebody please correct me if I'm wrong.
But if through exchanges, it's always better to just choose the most popular options like the ones you mentioned. I'm puzzled how OP ended up with boomchange. Haven't heard of it.
