Loctite every time. I use 577 which is specified by my espresso machine manufacturer in the maintenance section of the handbook. I think 567 is very similar but slightly lower shear strength, which shouldn't be an issue in these sorts of application.
Strictly speaking, teflon tape is a thread lubricant, but often used as a thread sealer as it is so often ready to hand and loctite aint.
Both are a bit of a nuisance to clean off if you have to remove the fitting for re-use, and possibly teflon tape is easier.
Provided you fill a few threads with loctite, you can guarantee it will be 100% sealed - no guessing or doubt.

577 conforms to WRAS/BS6920 so happy to use it as it is also used in the original manufacture of the machine.
Don't think 2046 is marketed where I live, but Loctite have a number of region-specific products to comply with differing local test standards.
As the machine I own was also imported to the US as well, I wonder if they used a different product for that market ? Somehow, I doubt it as the same maintenance book covers both 230v and 110v versions of the machine.

Blue Monster Plumber tape sold at Lowes, it is a bit thicker than white variety. I cant find the info on this tape, if it is safe to use in steam/brew boilers. I also found Oately MEGATAPE, but also cant find whether it can be use for espresso machines. Or I should just use white type?
That's because they work on prosumer espresso machines all the time and know what a PITA thread locker is when you are trying to removing a fitting. When I help design espresso machines, I always specify Teflon tape is used wherever possible now. It takes the manufacturer much more time on assembly, but so much better for the customer years down the line.
Would I use threadlocker.....only if I had no other way!!
