I have been sewing triangles for more than 60 years and never heard anything bad about them until I joined this board. I also belong to a very large quilting group, well over 100 members and have never heard anyone complain triangles, in fact one young quilt maker just showed a very large quilt made entirely of small 1/2 square triangles.Put your 2 pieces together properly before you start sewing, do not just fix one end and expect to match the rest while you have part of it under the needle. Feed your matched pieces gently and take a bit of care at the finishing end because they have a tendency to pull to the side and narrow the seam. Remember you are the master and it's just another piece of fabric you are sewing. It's very easy if you don't get yourself in a tizzy. I know you can do it!
