Best unloaders(bypass)

[ChechenWolf]

Hello, i want to change my vrt3 unloaders, because they are living near 1 year, and so i dont like them. I want to choose between Pulsar 4 https://www.kleen-ritecorp.com/p-64...-with-ez-start-10-5-gpm-4500-psi-3-8-fpt.aspx and RM suttner st 261 https://www.kleen-ritecorp.com/p-3977-suttner-regulator-3-8-pressure-sensitive-4060psi.aspx . My pumps working at 2800 psi(200 bar) and 1 is able to get 3600 psi(250 bar). What's the better choice or there is even better regulators?
