I've got mostly Craftsman stuff. A few things I have are S-K, Snap-On and Mac. I'm a deal-hunter by nature so I now usually buy tools used. This is after initially getting started with various Craftsman socket/wrench sets to end up with a very comprehensive set.
The advantages of Snap-On in particular were lost on me initially. Over time I realized there are a few good things about them. They do push the envelope for innovation, coming up with ratchets that need very little degree movement to work or the shapes of socket walls etc. They do something new that works, then they are copied (nature of the world). Also, in general and over a long time the ratchets & wrenches are more comfortable in the hand. For someone that doesn't wrench for a living though I'd see no reason to go with Snap-On, Mac or any other tool sold primarily through a for-profit middle man (truck vendor).
I recently picked up a Mac 3/4" drive set with extensions and drive adapters for very little ($85) though craigslist. I didn't need the set, but bought them anyways after coming across them. When it comes to hand tools, I'd rather have it and not need it than need it and not have it.
I'd say buy a known brand for what you can afford from a store that's close to you. Replacing broken ones won't be difficult at all then. Generally, getting a warranty through a truck vendor can be a pain, as they don't make money from you and don't have a good incentive to help you because you don't give them weekly profits. Truck vendors will have access to some very specific, very useful and impressive tools. If you ever need one of those, they may be the only source...but it's doubtful you, the OP, will be in a situation like that.
Sometimes, what I do for sizes I don't use often is buy a cheap HF set or similar. Then, if I ever break or wear one out I replace just that one with a higher quality name brand. But I always look at craigslist, garage sales etc for tools and buy things I could use or replace cheapies with. Many times older tools were made better, even basics like hammers. I'll buy a cheap head of an old used hammer and put on a different handle than what I have to make things like mini-sledges and other useful "custom" pieces. Also, sometimes having a cheap wrench is great, as you can grind it to fit some unique clearance and not feel bad.
