Is the Roland TD-1DMK worth the extra $200?

If dual-mesh snare and toms and coach functions with onboard scoring matter to your playing, yes. The delta buys you real upgrades, not just branding. If you don't need those specific features, the Alesis Command Mesh SE is the smarter buy.

Which is better for beginners?

Both are solid upgrades from entry-level kits. Your choice should come down to which module and pad feel appeals to you more — there's no clear beginner-friendliness winner at this tier.

Can I connect either kit to a DAW?

Yes — both. The Roland TD-1DMK and Alesis Command Mesh SE both offer USB-MIDI, so you can plug directly into any modern DAW without additional hardware.

Which has better pad feel?

Both kits use similar pad technology at this tier. If you want to dig deeper, look for dual-zone capability — it lets you cross-stick on the snare, which makes practice sessions feel more like playing an acoustic kit.
