Yeah, level scaling kills the game. I think we can all agree on that.
You can have fun for a while, then at some point you'll only notice that wherever you go it's just the same, you'll just face harder versions of critters you've met before with no connection to "realism" whatsover.
I haven't tried Tendo, but I still strongly suggest Requiem.
It's tried, tested, and it really doesn't need much tinkering with - the mods I use with it cover areas that don't overlap.
Its real merit is that it doesn't just remove level scaling, it tries and, within the limit of the engine and the world, succeeds at making the world itself make more sense.
When you escape the prison you are a hobo and you literally have the problem of making a living.
You'll feel that, because you won't be able to go hunting Daugrs in tombs, they will slaughter you.
This phase might even become boring at some point, but getting out of it will provide a real sense of achievement, and the game more or less starts a second time here, because then you will be able to face the first tier of monsters, so to speak, and you'll finally tackle quest and dungeons for real.
The more fearsome monsters will need high level chars, or really effective builds, and/or the use of powerful artifacts (which DO exist in Requiem, those are reworked as everything else).
Finding them becomes a meaningful goal.
Slaying a Dragonpriest is the stuff of legend, not a minor thing that happens to you because of level scaling. Yet it might become even "easy", when you're powerful enough yourself.
I think this is certainly the best way to play Skyrim.
