Porter Ports or Cabledyne Cryo Hubbell 5362

Which outlet grips the power cord better between the Porter Ports and the 5362? The Porter Ports are supposed to have hospital grade contacts and the 5362 is industrial grade, so there might be a difference. Can anyone who has both do a quick test?

Both are tight, IMO. Hubbell 8300 Hosp. grade and HBL5362. The Furutech outlets are even tighter.

Looks like Cabledyne has the Hubbell HBL5362 on sale. Best price I could find.

lall's ranking of these receptacles is a bit odd:
" My overall ranking based on the above tests are as follows:- 
1. Cabledyne Cryoed Hubbell 5362
2. Hubbell 8300 (non cryo) – old stock all copper version
3. Porter Ports
4. Legrand
5. FIM Gold 880"

lall visually verified that the Porter Port was identical to the Hubbell 8300H with the same copper backstrap. A bit shocking that the non cryo'd Hubbell beat the cryo'd one!

I've got a couple vintage stock Hubbell 5362s in my system and intend to get some vintage 8200Hs shortly (identical to 8300H except not a true 20 amp connector as the extra clip deleted.) I've got to up my boutique outlet game a bit as I have 8 dedicated lines, but other than a variety of Hubbells, just a lone Maestro outlet. I'd like to get the Cabledynes, but limited to 2 at $35 each plus $10 shipping ($80 for 2). Up from $25 per unit to $45 now; the price of fame.

A shame theaudiotweak did not report back in detail on the single outlet HBL5361s. I've unfortunately noticed with my own dual outlets that one receptacle tends to sound a tiny bit better than the other. With 5361 you know you're getting the job done with just one outlet to choose. With duals it seems like one wire is connected fairly direct to one outlet while the other is reliant on the clippable tab to conduct to the outer
