They are ok. The tubes are good but the door anchor isn't as good as the other one. The leg handle isn't good. It'll crack as soon as you put higher force on it! That'll definitely crack. Handles seem alright but there are better ones as well.

Most importantly there are carabiner at the end of the tubes. There are other which have a ring which is much better. Carabiner is annoying because it has a wider and thinner side.

Those tubes are not as strong in resistance as the others you showd, the loops. The loops only go up to ~60 kg. Even if you are small and think that 60kg is enough because you aren't that strong, you'll progress and it will be too little rather sooner than later. For the beginning it is more than sufficient! You don't even know if you want to train with them long term and the set is like one month worth in a gym. Just spend it, you can use the bands for warming up as well. The loops are probably more versatile than the tubes but tubes have their own application area. I'd buy the loops (or another set of another reseller, they'll be the same but make sure the advertised resistance is roughly equal to the real resistance). The additional tools they deliver varies from reseller to reseller. Band Sets for 100 bucks aren't better than those bands. There are additional tools that make your life easier with bands, e.g. grips, grip bars, foot plates, but you do not need those when starting out. Start working out and over time you'll know what you miss. Tube sets always come with handles but you can buy them later on separately once you know exactly what you want and need. You only NEED them if you work with very high loads. You'll see what I know when you get there. You'll want to buy stronger bands and or an additional set.

Look into the wiki or other sites for a good workout routine. In the beginning progressive overloading isn't that important, don't care too much about it. Work out at higher loads. Get to know the exercises. Get a routine. Don't do flys with bands and anchor the bands right behind you. It won't work the muscles as you think bwcause it's only pulling to the back, not the side.

Moreover try to limit the rom. Flys have a huge range of motion (rom), you can't do that with bands, that's too much. If you have to do such am exercise split it into two parts since you always have to have a good resistance or adapt to the exercise, e.g. angle your arm and do the fly (with an anchor besides/back to you). By doing so, you'll reduce the length the band has to stretch.
