I would offer a slightly different perspective. Don't get hung up on "name brand" vs. "generic". I think it is more important to have a set of clubs that fit you properly, concentrate on the basics, and take lessons from a professional if you can so you don't ingrain bad habits.
Name brand clubs do not automatically allow you to become a better golfer. If you have trouble getting the ball up in the air high enough a fancy name on the club will not help. What would help is a "game improvement" style club head with a cavity back, low center of gravity, and a shaft that has a softer tip and a low kick point. If it has a fancy name or not does not matter.
If you have trouble slicing the ball then a club head with a greater amount of offset at the hosel might help to straighten things out. Don't forget the lessons but some help can be obtained from the style of the club head. Some slices and hooks can be corrected by having the "lie" of your club heads adjusted to fit your swing. If the heel of the club touches the ground first then it slows down and the toe of the club starts to swing around. That closes the club face and would cause an otherwise straight shot to suddenly hook. If the toe hits the ground first then you get a slice.
If your clubs have too heavy of a swing weight then you might not be able to square the club face at impact and hit slices. too light of a swing weight and you will not be able to "feel" where the club head is during the swing. If you are not big and strong then overall lighter clubs would let you swing the club faster and hit it further.
If you have smaller hands then a standard grip might be too large for you to get the shaft positioned properly in your fingers. That prevents yo from releasing the club properly so it is not square at impact and you lose club head speed.
There are more things to consider but by now you have got the point that none of these things have anything to do necessarily with "name brand" vs generic clubs. Please don't go buy the cheapest clubs you can find and I would not advise spending a ton of money on a fancy name if it does not come with a custom club fitting. Finding a good club fitter or pro who can fit you with a set of clubs is money better spent.
I play to a 6 handicap, only play a couple of times a month, and I use clubs I made my self from various component companies. It so happens that I'm an engineer and have all the equipment necessary to measure a clubs swing weight, frequency (stiffness), measure the flex points of the shaft, measure and adjust loft and lie, etc. I build clubs for myself and friends. The point simply being that you can play well with anybody's club if it fits.
What name brands will give you is the newest in technology because they have the funds to do the research. However, if they don't fit your needs then it does not matter. Focus on getting a good club fitting, get the lessons to teach you to swing properly, and then buy the best clubs you can afford.
