Both.
And don’t forget that it hasn’t been serviced for 12 years.
JWST is more of a gamble as it can’t be accessed.
Yet... If SpaceX can get on-orbit refuelling going, it is perhaps feasible to send a Starship to JWST at the L2 point, is it not?And don’t forget that it hasn’t been serviced for 12 years.

First images scheduled in a press conference for 12th July.
"These first images will include a deep-field image peering farther into the past than ever before, scientists said during the briefing. NASA will also release Webb's first spectroscopic data — precise data on the type of light that Webb detects that will allow scientists to learn more about the ingredients of distant cosmic objects. This data will include Webb's first spectrum of an exoplanet, scientists said."

JWST is not, going to L2 is probably a suicide mission for Starship, especially if manned.
I'm booked in on 12th in the South Downs Planetarium for one of the first showings of the JWST photos. Can't wait.

^ Excellent!

This is the initial target list that they'll be showing images of:
Carina Nebula: The Carina Nebula is one of the largest and brightest nebulae in the sky, located approximately 7,600 light-years away in the southern constellation Carina. Nebulae are stellar nurseries where stars form. The Carina Nebula is home to many massive stars, several times larger than the Sun.
WASP-96 b (spectrum): . WASP-96 b is a giant planet outside our solar system, composed mainly of gas. The planet, located nearly 1,150 light-years from Earth, orbits its star every 3.4 days. It has about half the mass of Jupiter, and its discovery was announced in 2014.
Southern Ring Nebula: The Southern Ring, or “Eight-Burst” nebula, is a planetary nebula – an expanding cloud of gas, surrounding a dying star. It is nearly half a light-year in diameter and is located approximately 2,000 light years away from Earth.
Stephan’s Quintet: : About 290 million light-years away, Stephan’s Quintet is located in the constellation Pegasus. It is notable for being the first compact galaxy group ever discovered in 1877. Four of the five galaxies within the quintet are locked in a cosmic dance of repeated close encounters.
SMACS 0723: Massive foreground galaxy clusters magnify and distort the light of objects behind them, permitting a deep field view into both the extremely distant and intrinsically faint galaxy populations.

Just a heads up, I believe that Biden is going to release the so called "Webb deep field image" tonight at 5pm eastern time USA, so 10pm UK time, the rest of the images will be released tomorrow.
This is hopefully going to be mind blowing.
You, er, have a hotline to the President?This is hopefully going to be mind blowing.
World Science Festival is doing a talk on it tomorrow too, kicks off at 8.30pm BST.
