I use both. Shavette mainly for travel but also for my head because shaving my head dulls the SR too fast for me. You can get away with a wider range of angle with the shavette so you may not have really learned the correct angle yet. I prefer the SR over the shavette and can get just as close of a shave with the SR and the SR is more comfortable. If you have been getting good results with the shavette, work on the angle of the SR. Eventually you will be able to feel and hear the angle on the SR.
