Long term windows Not so long term budget

I'm getting more and more confused with each post I read in terms of window manufacturer quality. I'm getting quotes on replacement windows. I thought that Simonton and Alside had decent windows in their upper lines. I plan on staying in my house for another 20-25 years. I don't have a big budget. Am I barking up the wrong tree looking at Simonton Reflections 5500 series or say Alside UltraMaxx as my windows of choice? Thanks for your thoughts.
