MSI GT63 Titan 8RF vs MSI GP73 Leopard 8RF

[Sir Sparhawk]

I'm looking at getting a Gaming laptop and have finally narrowed it down to my final two choices (for now). There is only a £100 price difference between them and was hoping someone could help me make my final decision.

They both pretty much share all the exact same specs.

£1,499.99
MSI GT63 Titan 8RF:
15.6" FHD (1920*1080), 120Hz wideview 94%NTSC colour Anti-Glare 3ms
Intel®Core™ i7-8750H
GTX 1070, 8GB GDDR5X
256GB,NVMe SSD1TB (SATA) 7200rpm

£1,399.99
MSI GP73 Leopard 8RF:
17.3" FHD (1920*1080), 120Hz wideview 94%NTSC colour Anti-Glare
Intel®Core™ i7-8750H
GTX 1070, 8GB GDDR5
256GB SSD 1TB 7200rpm HDD

Other than the chassis the only real difference between them is one has a smaller screen with a IPS (at least I think it's IPS) G-SYNC screen.
And the other is a TN panel without G-SYNC

Any insight on the differences that can be expected in performance is greatly appreciated. I.m somewhat worried about thermal throttling and think the first option may be slightly better
