Glencairn vs. Riedel.....

This is my first post on this forum. I am a noobie here but not to the world of Scotch however. I have a fairly decent collection of Single Malts and have been drinking my share of Scotch for many years. Some very good and some...well lets just say I wont be adding them to my collection ANYtime soon! I have both glasses from Glencairn and Riedel and have tasted many scotches out of both types....as well as a few other glasses.

Id like to hear from the members here which tasting glass they prefer and why?
I have tasted the same SMW out of both glasses, head to head, and gotten different notes and tastes from them both.
Anyone else done this and gotten the same results?

Thoughts?
