I used LBC to buy bitcoins when there is no enforced KYC requirements to trade there and it was most reliable at that time because most exchanges didn't have fiat deposit for many countries after that 2017 lot of local exchanges popped up so we can get better deals for fiat than LBC in the recent times.
I used LocalBitcoins for my first purchased Bitcoins too. In fact, everyone should create good trading relationships from the P2P marketplaces. One day, you won’t be needing the platform to trade with one another. It would be a simple peer to peer transfer, preferably in person.
