rMBP mid 2014 vs rMBP early 2015

I just want to make sure I'm not missing any key differences between the two models here:

• force touch track pad
• broadwell CPU + graphics
• sligthly bigger battery

I'm leaving Canada for Switzerland (for 6 months) in 2 weeks and I need to get a new laptop ASAP as my old one is dead, but haven't been bothered by it to much because I have a nice desktop with multi-monitor...

Unfortunately money is tight right now. So I'm considering the mid-2014 model...
