Launch X431 Pad VII vs X431 V+ with X-prog3?

What’s the difference between Launch X431 x-prog3 with X431 V+/V/Pro3s+ tablet and Xprog3 with X431 PAD V/PAD VII/Pro5?

X-prog3 is compatible with Multiple X-431 Series Diagnostic Tablets (X-431 V, X-431 V+, X431 Pro5, X431 ProS, X-431 PAD V, X-431 PAD VII, X431 Pros3+ etc)

X-prog 3 or the GIII with X431 V/V+/Pro3s+/Pros has the same immobilizer coverage as x-prog3 with PAD VII/PAD V/Pro5.
