Is the Roland TD-17KV2 worth the extra $579.01?

If prismatic sound modeling from td-50 and digital snare (pdx-12) for deep expression 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-07KVX 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-07KVX.

Can I connect either kit to a DAW?

Yes — both. The Roland TD-07KVX and Roland TD-17KV2 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.
