I use flat bands like that exclusively I think mine are also one metre long. That means I can't easily compare them to tubing.
For front chest pull and similar pulls 1m is really too long, so you can't hold the bands by the end. By starting the pull with your hands progressively closer together, you also increase the difficulty, so it's not all that bad. Depending on your arm length, they might work OK for back press.
Deadlifts and squats work quite well with the heavier bands since the flat shape is more comfortable, but deadlifts still benefit from some kind of handle because the part of the band you are holding onto also stretches.
One thing I like to do with longer bands is the side-press; an overhead press with the band looped round the right hand and the left foot (or vice versa).
