Regulator Rectifier which one is better? Celox or Electrex

[Gra900]

Hi
Has anyone any experience of this product
https://www.ebay.co.uk/itm/283705053557
which is £30 as opposed to this one
https://www.electrexworld.co.uk/acatalog/RR33-Regulator-Rectifier-Yamaha-XS400.html
which is £78
Is it worth 2 x the price?
I have a 4G5 1982 XS400 SE, alternator coils test OK with 1.1 to 1.0 ohms, not charging
Thanks

Haven't used either but the electrex one has the correct connectors to wire directly into the harness. Saves a headache.
