Need Purchase Help

I'm going to purchase on B&H because I save $$ in Sales Tax and they seem to have good prices, the Apple store was much higher with all the additions plus sales tax, etc.

an i7 is faster than an i5 correct?

The battery is not removable in the touch bar version...is that a bad thing and should I care?

I'm torn between the MacBook 13" late 2016 non touch bar.

• 2.4 GHz Intel Core i7 Dual-Core
• 16GB of 1866 MHz RAM | 1TB PCIe SSD

or the 13"

• 3.3 GHz Intel Core i7 Dual-Core
• 16GB of 2133 MHz RAM | 512 PCIe SSD

I also read that the ram in the non touch bar MBP are not the same and slower than the touch bar models

Anyone care to weigh in? Thanks in advance for your suggestions.
