I have a G30 and it feels so good in my hands and is so utterly reliable and accurate that I wouldn't dream of trading it for a G30SF for an ever so slightly shorter grip frame.
The G30 is a dream .45. One of the very best Glock models you can buy, in my view.
If there are potential issues related with the G30SF, then I would wholeheartedly recommend choosing a G30 and never looking back!
