I have an assortment of Fragola, Aeroquip, Earls, Jegs, summit, and even some cheap ebay fittings. Usually use Jegs housebrand braided stainless hose. Been putting them together w/ basic wrenches and a bench vise for years. Some of these fittings I'm still using are 20 years old. Even the cheap ones are all at least 5 years old.
I've had one length of hose fail...started leaking through the braid and halfway down the length of hose. That was after many years of service w/ pump gas.
