I like buying kits and have always had good experiences with them. When I try to buy yardage on my own there is always one fabric I can not find. I really like Connecting Threads. One kit had so much fabric I was able to make two of the pattern. My LQS is very generous with their cuts to.
I am willing to pay a little more for them to do the work. I would spend it in gas running around looking for fabric so its a trade off.

I bought a Quilt in a Day mini-Dresden plate kit by Eleanor Burns. I made the plates as instructed and after attaching them to the background squares, the block ends up being 6" square. Problem now is that the sashings for the squares should be 6" as well right?

Problem is that the sashings are made of the same fabric as the Dresden plate fabric but the kit only came with 5" charm squares. Sashing strips have to be made by cutting the 5" charms into strips and piecing them together. ugh!

Also the directions that came with the kit assume the fabric being used is in strips and not 5" charms. double ugh! Thinking of sending a message to the manufacturer to ask why did they packaged the kit this way.

See what they say. Couldn't hurt.

I did one kit. There was enough fabric but the instructions were very poor. I made the same project again, but used my own fabrics and modified the instructions with a much better result.

I bought some kits from Connecting Threads. Both had plenty of material. I like them for the ease of not having to search ten stores for the "just right" fabrics. I bought them when I worked and time was scarce. Now that I'm retired, it's fun to have things delivered to my doorstep. Depends on what you want/need. I haven't used kits from any other companies.

I LOVE buying kits from Connecting Threads, and buy them when they go on sale...can not beat the price and when you're on a quilting budget it is very worth while. The kits ALWAYS have had quite a bit left over and I buy the kits because their fabric choices are what caught my eye to being with, so I certainly am not interested in changing out fabric.

I have bought kits from Connecting Threads and Keepsake Quilting and was very pleased with the fabric and the amount sent. I like the convenience of not having to go to several places to find matching fabrics. It is a timesaver for me.

I bought a Ryan Mckenna quilt kit from Nancy's Notions, Love it. It would be too time consuming to find the right fabric and it was at a good price. I saved over 100$ getting it from them vs other places.

The very first kit I bought at my LQS was short of fabric when I started cutting. Now, if I buy kits, which I rarely do as I love the search for just the right fabrics, I *always* immediately open it up when I get home and check the yardage in the kit with the pattern to be sure there aren't any shortages.

I often like the pattern but don't like the colors in the kit. I prefer to buy the pattern then search for fabric I like or dig into my stash to see what I have. I guess the fun of selecting fabrics and auditioning them is more important than the convenience of a kit. However, if I liked the colors/fabrics provided in a kit I would probably try the kit.

Mostly I don't buy kits because I have so much fabric, but there was a table runner pattern or kit I saw at a local store, and I just bought the pattern, thinking I would have plenty of fabric, but I don't have the colors I wanted, and now wish I had just bought the kit and been done with it. Live and learn!
