Since choosing a PC case is personal choice, pick the one that you like the most.
Well, any case that has meshed/grilled front panel is good for proper airflow and cooling of the PC. And for fan combination: front & bottom - intake; top & rear - exhaust. Also, 140mm (same spec) fan moves more air and does it more quietly than the 120mm fan. So, when possible, get a case that supports 140mm fans all around.
While i can suggest specific cases based on my own personal opinion of their beauty and practicality, my taste may not agree with yours and in the end, it's your PC case, not mine.
I'm one of the few who prefers full-tower ATX cases over mid-tower ATX cases and thanks to this, my Skylake and Haswell builds sit in a full-tower ATX cases from Corsair. To be more specific: Skylake is in Corsair 760T V2 Black and Haswell is in Corsair 750D Airflow Edition. Also, i have aftermarket Demciflex filter kits on both of them for dust catching.
As far as both cases go, both are perfect for my needs. Lots of internal space, easy to work in, plenty of 3.25" external bays, great cable management, superb airflow, compatibility with Demciflex custom filters, great looking, and the list goes on and on.
