Bluestar RCS vs. RNB

[bguy2008]

I am considering a 36 inch, 6 burner Bluestar range. They offer the RCS and RNB versions of this range, with the primary difference being a max btu rating of 18k on the RCS vs. 22k on the RNB. My question is this: does the difference really matter if you are not a professional chef? The price difference is substantial (RCS is less). If anyone out there has experience with the RCS, please share. Thanks!

We have a Bosch dual fuel range where the hottest burner is 15,000 btu, and I rarely if ever use it on the highest setting other than to boil water or get a pan sizzling hot quickly. I'm sure that for professionals it's different, but I can't imagine actually cooking at the 15k maximal setting.
