which laptop of the two should i get? and should i get the m2 sata ssd with my HHD?

Ihave finally decided which two laptops I think will be best for me and my budget. they are the Clevo p157sm-a and p150sm-a (details below) built by www.AVAdirect.com. I just have a few final questions like should i stay get the m2 sata SSD or not and if so how much will I really need if I am going to be mostly gaming and don't think I can afford a reasonable size SSD for storage. Also, what is the actual differences between the two models???? Lastly, is their any other laptops that have similar stats for about the same price and would be better? Thank you for your time.
