There are plenty of good windows. You are going to have to shop around before trying to drive the bargain anyway, so I won’t say this or that is better.
On the technical side make sure you get a window that has a slim enough profile that it doesn’t go beyond the plane of the drywall.
If it is paint grade I rip mdf down for the jamb trim and round it over with a 1/8 router bit then case it with pine or mdf.
Stating the obvious, same principle for stain grade, except use clear wood on both.
