In all my years as a carpenter, I'd have to say Andersen makes the best. Like others, they have different lines, glass options, trim, etc. What stands them out is the quality of Mfr.
Let's say you're installing 9 identically sized windows. With Andersen, you can measure just 1 of the and cut all the trim, ahead of time. Knowing it'd fit every window.
We did a job at a big time country club and the main dining hall had a huge gable wall, with 3 rows of windows, some arching. It was a nightmare to get everything aligned (using lasers). We had to fudge so many things, even planing some of the jambs so the trim looked ok. These were all Pella and that single wall was ~$50k.
ETA: Stay away from Renewal by Andersen. They DO NOT carry the Andersen warranty, it's completely different.
