1. The F-35 has a 600 NM combat radius on INTERNAL fuel.
The griffen has a 431 NM radius
Performance

Maximum speed: Mach 2 (2,204 km/h, 1,372 mph) at altitude
Combat radius: 800 km (500 mi, 432 nmi)
Ferry range: 3,200 km (2,000 mi) with drop tanks
Service ceiling: 15,240 m (50,000 ft)
Wing loading: 283 kg/m² (58 lb/ft²)
Thrust/weight: 0.97
2. The F-35 can carry an insane amount of weapons when loaded with internal and external. I would dare say it carries a lot more than a griffin.

Armament

Guns: 1 × 27 mm Mauser BK-27 Revolver cannon with 120 rounds (only available on single-seat A/C model)
Hardpoints: 8 (three on each wing and two under fuselage) and provisions to carry combinations of:
Rockets: 4× rocket pods 13.5 cm rockets
Missiles:
6× Rb.74 (AIM-9) or Rb 98 (IRIS-T)
4× Rb.99 (AIM-120) or MICA
4× Rb.71 (Skyflash) or Meteor
4× Rb.75
2× KEPD.350
2× Rbs.15F anti-ship missile
The F-35 carries the Griffins max missile load internally with 6X AMRAAM
Imagine an F-35 in NON stealth Mode with 6X AMRAAMS internally and
6X externally. 2X AMRAAMS on a Inboard pylon dual rack 1 on the middle rack and a AIM9X on the out board rail. The F-35 In non stealth mode destroys the griffin In both range and weapons load.

3. If your going to consider mach 1.2 super cruise then you must add the F-35 into the same boat. The plane has marginal super-cruise by your definition.

“Griffiths declined to compare the F-35 to the F-16s he once flew. But he noted the F-16 is only technically an 800-knot and Mach 2.02 aircraft. In practical terms, most pilots will never see speeds above 700 knots or Mach 1.6 because real-world load-outs don’t allow it.

The F-35 can’t supercruise like the F-22 Raptor, but the test pilots have found that once they break the sound barrier, supersonic speeds are easy to sustain.

“What we can do in our airplane is get above the Mach with afterburner, and once you get it going … you can definitely pull the throttle back quite a bit and still maintain supersonic, so technically you’re pretty much at very, very min[imum] afterburner while you’re cruising,” Griffiths said. “So it really does have very good acceleration capabilities up in the air.”

Do you know very much about the F-35?

??

It is my Humble opinion, that Taiwan should spend all of the political capital at there disposal to acquire,

A. F-35bs is a large quantity AV-8s and F-35bs are some of the only fighters than would give China great difficulty in totally destroying the defending air forces.

B. Like mentioned above Taiwan should purchase dirt cheap surplus harriers as the Lo in a Hi lo mix. maybe 200 harriers and 100 F-35Bs.

This would ensure that short of total capitulation, or the firing of nuclear weapons The Chinese would not be able to land forces across the straight unmolested. A pop up F-35 carrying NSM or a even a Av-8 Firing SBD at your landing ships is a Chines nightmare.

I would Hide them in Mountain tunnels, In grass clearings, I would even build surplus hangers in commercial areas ( parking lots). I would put some in HAS.
I would put the supply train on trucks Hidden in revetments or in underground warehouses. And I would support it all with a fiber optic secure network. let the Chinese waste thousands of SRBMs on patriot batteries, and air fields. But again all of that would require money and common sense.
