This! lol,
I am very guilty of not being consistent I think 
I am more of an “emotional” type review writing (not that I write a lot of reviews lol). My favorite way to write now is to just stream of conscious write while listening. This definitely makes for inconsistancies due to picking up nuances as I go through different music and my brain acclimates to what I’m hearing. Plus I am usually imbibing some whiskey or rum…sooo… yeah 
But, I think the best you can do is find a reviewer that has similar likes to yourself, plus has reviewed things that you either have had or heard and you both had similar thoughts on the gear. That way if they like something, you at least have a baseline for a potential match (this does not always work out, but is at least better than going in blind).
