I'd like to get some thoughts on which HM synthetic(readily available) people think is the best and why?

PPHM because I like yellow bottles and have had a lot of success with pennzoil.

Valvoline Max life. I don't know if it the best but I'd use it.

I suppose the answer to your question really depends. For mending seal weeps or questionable gaskets I prefer Valvoline Max Life either in the red bottle synthetic blend or the silver bottle full synthetic with the red cap. For an older engine with borderline oil pressure I prefer M1 HM. Really the best course of action though is to fix any leaks or seal issues and then run a normal oil. My 4Runner has made it to 329,000 miles on 99% normal every day conventional oil. Doesn't leak or burn a drop.

I can say I've had luck with Valvoline's FS with Maxlife. I would say that if it cures a small oil leak without having to do any work, it is a win. They might all work well, but Maxlife has worked for me.

I use a quality synthetic already and don't know I'll ever see the need for high mileage blend. High mileage blend sounds like a marketing scheme. lol

The "best" is very subjective, but I have used PPHM, M1HM, and VMLFS. For what it is worth, I prefer the Valvoline Maxlife FS. Bottom line for me is that it is spec'd for my cars/trucks and has been better at reducing, slowing or stopping leaks/weeping than the others in my cars that have needed that. I used it now for everything regardless of mileage.

There is no best, but I like Valvoline MaxLife. Simply put, my engine was smoother with it than other oils.

Which one cleans the best and which one reduces consumption? I hear good things about M1 cleaning and RP hmx for slowing down consumption. I use about 1 qrt every 3k or less, give or take some so looking for something to reduce consumption.

The best 'HM Synthetic' is Maxlife.
The best synthetic for a high miler is Redline.

ML has slowed leaking and burning in every vehicle I've used it in, including the synthetic version-but I'm not sold on the extra $ over the synthetic blend. When it's $7-10 more a jug, I'm not sure the synthetic ML is that much better. Kind of like M1 AP.

Here is a link to the MaxLife Full Synthetic

http://content.valvoline.com/pdf/valvoline_full_synthetic_with_maxlife_technology.pdf

The 10W30 looks good to me, but not sure of your climate, so only down to 0F (-20 C) for cold starts, otherwise go the 5W.

Another vote for Full Synthetic Maxlife.
OTOH, I even had luck with Supertech 5w30 High Mileage. Eliminated oil consumption (it was 1qt/5k miles) and stopped a valve cover "sweating" syndrome.

If it must be "synthetic", a marketing term, then any CK-4/SN or CK-4/SM will do in your choice of viscosity.
Engines using these oils routinely go over 1 million miles.
How much "high mileage", another marketing term, do you need?
