CRT has many user configurable settings (fonts, colors, screen size, keymaps, and more); it also automatically saves these settings for you upon exit. CRT automatically saves previously visited sites for you as well -- a definite plus over the likes of WinQVT and Trumpet Telnet.
CRT also works extremely well as an external helper application for Web browsers like Netscape and Internet Explorer. Another of CRT's positive aspects is the fact that there are separate versions available for both Windows 3.x users and Windows 95/98/NT/2000 users.
