The short answer

Diadem Icon Infinity Pro Pickleball Paddle is the only one of the two with a published score (4.6); Ronbus Quanta R3 has none, so this is not a close call so much as an unmeasured one. Diadem Icon Infinity Pro Pickleball Paddle is best for: intermediate and advanced players who want maximum power with a forgiving sweet spot. Read the strengths below before deciding.

2 sources$140as of Oct 17

The Diadem Icon Infinity Pro is an elongated 16.5 x 7.3-inch power paddle with a honeycomb core paired with EVA and eTPU foams, a gritted carbon fibre face and a replaceable edge guard, weighing about 8.1 ounces. Verywell Fit named it best for power with a 4.7/5 rating, reporting strong drives and serves, good spin and a grip that stayed secure with sweaty hands. WearTesters scored it 8.5/10, praising its power and a surprisingly large sweet spot but questioning how long the painted grit will last. It suits intermediate and advanced players chasing putaway power with workable control; players who prioritise maximum spin or a long-lasting textured face should look elsewhere.

Strengths
  • — Dual foam core delivers top-tier power on both compact strokes and full swings
  • — Larger-than-expected sweet spot that forgives mishits despite a 7.3-inch face
  • — Replaceable edge guard adds durability and leaves room for lead-tape tuning
Watch-outs
  • — Painted grit on the face gave WearTesters only middling spin
  • — Face showed chipping and scuffing within weeks of testing
  • — High pop takes adjustment for players new to power paddles
Ronbus Quanta R3
Ranked #5 in Best Pickleball Paddles Under $150
Ronbus Quanta R3
Unrated2 sources$119.99as of Oct 10

The Ronbus Quanta R3 is the elongated shape in Ronbus's $119.99 all-foam Quanta line. Pickleball Studio rates the Quanta line a top-tier power paddle for the money but found it stiff and unforgiving until weighted with lead tape, and advises skipping it if you will not add weight.

Strengths
  • — Very light for an elongated paddle (7.7 oz, swing weight 111 as measured by Pickleball Studio)
  • — With 15 g of added weight it becomes "a legit top-end power paddle," per Pickleball Studio
  • — Priced at about a third of a Selkirk Boomstik, per Pickleball Studio
Watch-outs
  • — Small, unforgiving sweet spot out of the box, per Pickleball Studio
  • — Needs roughly $10-$30 of added weight to perform at its best, per Pickleball Studio

How they stack up

Diadem Icon Infinity Pro Pickleball Paddle

The Icon Infinity Pro pairs its honeycomb core with EVA and eTPU foams, a different construction from the full-foam GRUVN LAZR 16X Full Foam Power and the Ronbus Quanta R3. At $139.95 it sits near the top of this price band, above the Vatic Pro V-Sol Pro Series, and its 13.7mm overall thickness is slimmer than the 16mm Vatic Pro Saga Flash.

Ronbus Quanta R3

Like the GRUVN LAZR 16X Full Foam Power it is an elongated 16 mm foam-core paddle, at $119.99 against the GRUVN's $139. The Vatic Pro Saga Flash on this page is a hybrid-shaped polymer-core paddle at $99.99.
