$1,200-1,800 laptop, Y50UHD, Aspire V15 Nitro, GS60 Ghost Pro, or Eurocom M5 Pro?

I need a computer for intensive coding and simulations work, HD video editing, and some mid-level gaming. The simulations work requires at least 16GB of RAM, and I'd really like to have at least 128GB of SSD space for fast boot and a few programs. I've picked out the Lenovo Y50 UHD, Acer Aspire V15 Nitro Black Edition, the MSI GS60 Ghost Pro 3K-095, and the Eurocom M5 Pro. Until now, I've been scraping by with my macbook pro from 2010, but I find myself using my windows partition for all my intensive computing, so I'm switching to pure PC for the first time, and don't know much about these brands and their reputations. I'm looking for something to last me 4-5 years and to be portable enough to take with me in a briefcase. Does anyone have experience with these computers or brands that they might be able to help me choose? Thank you!

I do really love that laptop, but I'm looking for something a bit smaller and lighter, I don't want to go over 6 pounds and 16" wide as I'll be carrying it in my briefcase on my public transportation commute to work every day.
