I can’t comment too much on laptops, since I haven’t really read up on those (desktop user myself).
One big disadvantage laptops generally have is heat; causing the CPU to drop its clocks to protect from overheating. A cooling pad can help I’ve heard.
Doubt it’s a full spec desktop CPU in the second one though. Would probably melt the laptop and drain the battery in an hour 
Both would probably run the sim pretty well I would guess, but again, haven’t researched laptops a lot myself. Maybe someone else can chip in.
I would also check an AMD powered laptop (especially with their latest CPU’s), they’re a lot more power efficient.
