LOR is fine, but for me I've seen enough local politics that in general I don't view Israeli Rabbonim as objective on Kashrus. (American- Israeli Rabbonim are definitely less prone to this I think)
The latest one I've heard was a freshie who was told Rubin isn't fine, but Belz is a top-tier Hechsher. Good for him, not for me.
The freshie was lost.
"Politics" is an excuse not to care and eat what you want.
It take some effort, but you can usually figure out what's just "Politics" and what sticks
A litvishe not eating landau, a belzer not eating eida, a lunavitcher not eating shearis = politics (aside from shchita, maybe)
Landua, Rubin, Sheairis, Eida being consensus better while CCPT and BDTZ Rupshitz being the bottom of the barrel...not politics
