Is the Yamaha DTX10K-X worth the extra $4679.01?

If birch-shell tcs pads and dtx-prox module with faders for kit editing matter to your playing, yes. The delta buys you real upgrades, not just branding. If you don't need those specific features, the Roland TD-27KV2 is the smarter buy.

Which is better for beginners?

For someone transitioning from a starter kit, both are solid choices. If Bluetooth and app connectivity matter to you for lesson content and track playalong, lean toward Roland TD-27KV2.

Can I connect either kit to a DAW?

Yes — both. The Roland TD-27KV2 and Yamaha DTX10K-X both offer USB-MIDI, so you can plug directly into any modern DAW without additional hardware.

Which has better pad feel?

Both offer good pad feel at this tier — the Mesh pads on Roland TD-27KV2 versus the Mixed pads on Yamaha DTX10K-X come down to personal preference. If you've played both, trust your gut on which surface you liked more.
