Which is better for video editing?

The Stealth 17.3. Its 14 cores and 20 threads render and export much faster than the 4-core i7-11375H, and the larger screen helps with timelines. The 15M's 32GB RAM helps with previews but cannot make up the core gap.

Which is better for gaming?

They are close. Both use the RTX 3060 6GB and a 144Hz FHD screen, so frame rates are similar. The 17.3 has more CPU headroom for newer games, while the 15M is easier to move between rooms.

Which lasts longer on battery?

The Stealth 17.3, by a wide margin. Its 99.9Wh battery is nearly double the 52Wh pack in the 15M, so expect roughly twice the unplugged runtime for light work.

Is the Stealth 17.3 worth stepping up to?

Only if you want a desktop replacement. You gain cores, screen size, battery and ports but give up portability and out-of-box RAM capacity. For daily carrying, the 15M is the better fit.

Which is easier to carry?

The Stealth 15M. At 3.73 lbs against 6.17 lbs, it is about 2.4 lbs lighter and fits smaller bags, which matters if you commute or travel with it.

Can I upgrade the RAM later?

Yes on both. The 17.3 ships with 16GB and supports up to 64GB; the 15M already has 32GB, so it needs an upgrade less often. Check slot count before buying a kit.

MSI Stealth GS77 17.3 Gaming Laptop vs MSI Stealth 15M A11UEK-220

The Stealth 15M is the better pick for most shoppers: it is far lighter at 3.73 lbs, has twice the RAM at 32GB, and its i7-11375H boosts higher on light loads. The Stealth 17.3 wins on sustained CPU work with 14 cores and 20 threads, a bigger 17.3-inch screen, DDR5 memory, and a 99.9Wh battery that lasts far longer than the 52Wh unit. Owners of both note the Stealth line runs hot and loud under load, and the 17.3's 45% NTSC panel looks dull next to better screens.

Choose the Stealth 17.3 if you want a desktop replacement for video editing, compiling or heavy multitasking and rarely carry it.
Choose the Stealth 15M if you need a portable gaming laptop and want 32GB of RAM out of the box.
