Should be no issues with either, the only real difference would be aesthetics which would be entirely up to you. Both companies make a good product and providing the installation is top notch you should have no issues. That being said the best products in the world install be a lousy installer will cause problems so be careful on that end.

I almost didn't reply since I don't have exactly what you are asking for. But if someone else looking for sliding doors hits this thread....we got one from Basco and you can order them through Lowes (& use the 15% off moving discount coupon on their site if they still have it). I am happy with it and they have many glass options. I know most people prefer clear. We got the easy clean shield treatment and it does seem to work well.

Basco's web site, now with a luxury line and many frameless models they didn't used to have
