I disagree with you, I tested with numerous graphics cards manufactured between 2000 and 2016 and I confirm that display lists are slower than wisely used static VBOs on absolutely all drivers taking into account the static draw mode. I've seen lots of examples using VBOs like vertex arrays and this is exactly what you mustn't do if you expect better performance than in stream or dynamic draw mode.

Moreover, as I explained several times here, using display lists break shaders and/or OpenGL picking on some drivers.

In my humble opinion, some features are noticeably slower on Intel chips, especially FBOs. Some OpenGL 1.5 Intel chips don't support VBOs. Sometimes, they claim to support greater textures than they really do. There are even some restrictions on context creations under Windows with Intel. "nightmare" is the right word.
