LED bulbs for garage/shop

LEDs are like anything else: buy cheap ѕhіt, get cheap ѕhіt that works poorly for a short time until it dies. Buy good quality, get good quality that works well for a long time. There's a mountain of cheap ѕhіt on the market—avoid it. There's also a whole lot of really good stuff on the market. Buy products from companies who stand behind their product and constantly improve it, rather than from companies who import full containerloads of generic trinkets from China, slap a name on 'em, and cash in.

CFLs were never much good—and nobody ever claimed they were. They served one immediate need, they cut way down on the amount of power we use and pollution we generate to light our spaces. Light quality and other aspects of performance (cold start, etc) were poor. They served more or less adequately as a stepping stone, a sort of purgatory after stone-age glowing filaments but before LEDs were ready.

Tomorrow's LEDs will be better and cheaper than today's? Yes, for sure. But we're at a point where there are enough good, affordable, durable LED bulbs on the market that the total-cost-of-use math makes sense to buy now rather than continuing to pay higher electricity bills or put up with cruddy CFLs.

As for the thing about ZOMG LEDs ARE GONNA FRY OUR EYES OUT: Nope, read this. The Lighting Research Center at RPI is one of America's (and the world's) most highly respected research institutes in the lighting field—and deservedly so; they do good science there.

Effects on circadian rhythm (body clock): Yep, that's an issue being studied, and there's some substance to it. But in a world where we're surrounded by bioactive light sources (computer screens, phone screens, tablet screens, etc) this is not a sound reason for rejecting LED lighting in your garage or shop. The kind of light bulbs you use isn't going to determine whether you're gonna be out there at 2am rebuilding a carburetor.
