Would you recommend an upgrade from Sonar Studio X3 to Sonar Professional ?

X3 was such an improvement over X2 it's become the "Windows XP" of Cakewalk, where people stay on it because it's so much better than what came before. But what SONAR can do these days is indeed night and day. It's kind of like when you drive a sedan - it works, and gets you where you need to go. But then you drive a sports car, and find out that driving can be fun. 

sheesh...   the platinum upgrade is $299 from studio.  I was just going to go for the Professional upgrade at $99.  But then one year of updates is another $99.   I've been doing "ok" without any updates on my X3e studio...   and don't know the advantages of getting updates anyways.  Really not into spending the $299...     so many other areas to spend money on, you know...    what will I really be getting in terms of real benefit if I bite the bullet and spend the additional $200 for the Platinum version?

LIFETIME UPDATES!!!!

Hmmm..  ok you got me considering Platinum now...  when you're passing out nickels like they were manhole covers, it's kinda tough... was even considering jumping ship to another DAW due to the cost of the upgrade. 
 
Anyways, 2 things that really bugged me about Studio X3...  and please correct me if I've overlooked or done something dufus, which may be totally possible... I tend to just skip and ignore things that don't "work" for me right away...
1) the way that Prochannel was employed... you'd have your 3rd party plugins shown clearly in the FX Rack in the Track View, all visible right there (which is great), but the Prochannel plugins weren't visible there. This was hugely annoying, so I didn't even use them.
2) the console view, unlike many other DAW's, displayed only I think 4   3rd party plugins, and then you had to scroll to see the rest of them....  again hugely stupid and annoying.  There's plenty of space in the console view to list 10 or 12 plugins if you had that many. but they chose otherwise. 
 
I think #2 is addressed in the newer Sonars...?, but don't know about #1. 
 
Anyhow, I do hugely appreciate your input.  Thank you!  I have a hell of a lot to learn, and avoiding financial and time investment blunders is super important.
