Pellas are nice, but too expensive for what they offer. Not good in terms of price vs quality. Stay away from HD/Lowes American Craftsman series as well as Andersens, especially the Silverlines, or any brand that says XXXX by (name brand company).
Good window brands include but not limited to
Gorell
Okna
Sunrise <-Cadillac
Softlite
Simonton <-best bang for buck, jd powers best overall value, excellent warranty
Wincore
MW-decent but step above builder grade
Marvins
They all have different levels of quality, but read some reviews before. Make sure you get what U-factor, SHGC, all that you want.
Casement is the most effective at reducing air drafts and most efficient compared to DH, sliding, and SH windows. Fixed windows are obviously even more efficient.
Check the DP rating, they are higher on casements, you want a higher rating if your area is prone to strong winds/hurricanes. Also check the U-factor, different climates make different factors more efficient.
Check the glass warranty, you want a lifetime or double lifetime warranty, and many top of the lines will warranty against breakage, and nets also. Nets go inside on casement windows, make sure you know that.
ABSOLUTELY get the folding crank, some windows come standard, but some it's like a $4 add on. Make sure you spec it in case they don't come with the fold in handles.
I went vinyl, but got the Simonton 5500 series. It provided me with the best level where I could get a ROI in a shorter amount of time and didn't go above and beyond other houses in my neighborhood. The most expensive window typically doesn't pay off until forever, and usually by then they will be broken or technology will be better.
In some areas, if a window is within 16 inches of the floor, it must be tempered, I didn't want to get tempered, so did it myself instead of having a company do it. Check code for tempered glass.
Lamination is a new feature where the noise levels go down dramatically, may want to consider it for you bedroom windows or downstairs if you live on a busy street. I didn't go laminated, but the foam around the new window and a new window did wonders to the noise level.
Some windows also offer blinds within the glass so you don't have to dust.
Make sure you get at-least double pane, it does make a big difference, and ask for the thickness of the glass and the space between it. Also get it argon filled and low e if you can afford it. Triple pane is overkill IMO.
If you have wood windows now, remember when you wrap it the water hitting the aluminum will make a tin noise like sleeping in a house with a metal roof. But I still advise getting the opening wrapped. I forgot about that so now when it rains I can hear pitter patter unlike before when the wood sills absorbed the noise. I didn't get wrapped windows outside and wood inside, they are very expensive, and can still warp after time being a natural product. I went vinyl all the way, and it's also super easy to clean. After a few times opening and closing wood windows they will get wear marks, and I DESPISE sanding, staining, and clear-coating. They look nice, but not for me, especially not worth the money for me.
Remember if you are replacing windows, the opening will get smaller, by about an inch in width and length, so know this.
Any questions just ask.
Trimming, capping, installing windows isn't that hard. Plenty of resources online. I bought a brake off craigslist and went to town. Ended up wrapping my soffit and fascia too after I finished. It was about 8K cheaper for all the windows and fascia for me to do it and I know it was done right.
Shoutout to tornadocaster and IHI on here, they REALLY helped me with my brake and window install questions, I still appreciate it guys!
