Is the Roland TD-50KV2 worth the extra $2500?

If flagship v-drums module (td-50x) and digital snare, ride, and hi-hat matter to your playing, yes. The delta buys you real upgrades, not just branding. If you don't need those specific features, the Yamaha DTX10K-X 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-50KV2 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-50KV2 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.
