Top 5 Reasons:
- Lifetime Updates! Even if you leave Sonar for another DAW, you can always come back - even if it's 5 years later - and know you'll still be covered with the latest version.
- Sonar Plat is much more stable and noticeably more responsive than previous versions.
- Many, many new features since X3 (With new ones being offered each month).
- At some point, a Windows update (or other software incompatibility) will "break" a major function in X3 and you will be out of luck. With Platinum updates, any break is temporary (Until CW can fix it. Meanwhile, if it happens, you can rollback to a previous month).
- You can upgrade Sonar now or later. If it's later (assuming the lifetime updates offer has expired), you absolutely will kick yourself for not jumping on this deal when you had the chance.
