Depends what industry you work in. I've a fair bit of Facom stuff (spanners, vise grips, pullers, screwdrivers, etc), all about 10 years old, and so far nothing has broken.
Snap On is Snap On - yes it's good, and yes it's expensive. For much of the stuff I use, I can't justify Snap On prices these days; I bought a load back in the day, but I was earning more then, and had more disposable cash. Not so anymore. I'll still buy the odd bit here and there as and if I need it, but it's much more of a consideration these days.
Draper stuff I've never been fond of. Perfect example are the mini picks. Every set I've ever had, have twisted (inside the handle) and bent (at the tip). My Snap On ones have never twisted (although I have bent one a tiny bit, at the tip). I've a few Draper sockets, and they aren't amazing. Passable, but nothing to shout about. And a ratchet spanner crapped it's guts out barely a month or so from new. I do have a 1/2" drive ratchet of theirs that a customer gave me. I use it probably three times a year...
Britool - never used it. I think my dad had some old, old, Britool, but I've never had any.
Laser aren't bad. I've been using a Laser branded 3/8" ratchet, and metric sockets, everyday for a decade, and it's not once let me down. When I started out I bought the said ratchet and sockets, plus some water pump pliers, screwdriver bit set, a few extensions, some locking pliers, and a few other bits, and it's all still going strong today (apart from the locking pliers, which I lost!). I do have to tighten the nut on the water pump pliers now and again, but that's cos I'm too lazy to go buy threadlock. I've no idea what the tooth count is on my ratchet, and I actually don't really care - it's fine enough not to bother me, it's strong, and it's never been opened for servicing. I just dunk it in motor oil for a few hours every now and again (like, every few years!), and it's good to go! I reckon it cost less than £20, probably more like £15/£16, ten years ago - so that's £1.50-£2 a year use cost. Can't complain about that!
Halfords Pro/Advanced - been pretty happy with their stuff. I've had quite a bit of their stuff over the last 15 or so years - a full 1/2" drive set with extensions, UJ's, sockets, etc, a 1/4" ratchet that's used almost daily for a decade, a few sockets, a full set of flex head ratchet spanners (which I'm also led to believe are GearWrench made - although these are probably 8 years old?) and other bits and bobs here and there, and so far the only thing I've ever broken has been a 1/2" drive wobble extension (trying to undo a severely stuck manifold nut which didn't have clear access). Their screwdrivers aren't really anything to shout about, but the ratchet, socket, and wrench/spanner side of it is definitely useable professionally. Warranty is good on them, but beware they a) require the original receipt, and b) don't warranty any ratchet mechs. So bust a ratchet spanner or socket wrench, and your a bit out of luck.
So really, as ever, it boils down to what you need - Halfords are easy to get to (most towns have one, as do most retail parks), but Snap On is less quibble warranty (in fact I've never had a quibble from a SO warranty)
I do think that for home use and the hobbyist, SO is overkill - mainly on price. There's no denying their tools, for the most part, are great - but if you're just tinkering with cars (or whatever) at weekends, it's a bit OTT in my opinion. That said, even if you're an 83 year old woman, you should all own a SO ratchet screwdriver! Love mine so much, I bought two!
