I solely use localbitcoins. I have used local ethereum as well for once and twice to sell off aome of my ETH holdings, but localbitcoins is my regular platform. But this is only used when I need fiat money. Exchanges are made for trading and not p2p trade so these two platforms are different and serves different purpose.

My experience with localbitcoins is very good so far. I didn't have to face any issue till date. Probably another reason for this is that, I don't trade with random people. I have a fixed group of traders who are reputable and I always check feedbacks from their most recent trades. I don't deal with anyone less than 1000 trades.

Localbitcoins is a market leader in p2p trade and their escrow and reputation system is robust. That's why they remained as my favorite platform.
