Yeah, the ford 300 I6 is pretty legendary for its reliability. Right up there with the dodge slant 6. Just what you want in a pickup, IMO.

The 2.7 Ecoboost is a next-generation design and is a good choice for the F150. The manufacturers are not standing still, and they know what the issues are with the original 3.5 Ecoboost (and that engine had modifications also).

Intake valve clogging ... Varies all over the map. Some engines have had big problems, others have not. In the cases of big problems, some drivers have it happen and others don't, so it probably depends on driving patterns as well.

I've opted to stay away from this until it's figured out. The non-turbo non-direct-injection Pentastar in my van does fine for what it is. I have a friend who has a Pentastar/8-speed combination in a Ram 1500 pickup, and he reports 11-ish L/100 km in normal driving (21 mpg US), which is OK for a vehicle like that.

The Toyota 3.4 V6 was never known for being thrifty.

I've driven the 2.7 ecoboost in an AWD MKX and those twin turbos turned that sled into a rocket. I averaged 22 MPG in the 2 tanks I drove it.
My 2.0 ecoboost AWD sedan averages about 26 MPG but I can get 30 on a road trip. It's got plenty of get up and go but no where close to the 2.7

I've heard about issues with carbon fouling on valves with these newer DIT engines, but my bigger issue is with the HPFP and the numerous issues in most vehicles running them. The HPFP is the bigger reason I've opted to go back to a naturally-aspirated, large-displacement engine. Having had ~6 HPFP cars in the past 10 years, there were too many common issues for me to trust the technology to get me from point A to point B reliably, especially now that I've got a kid. I'm willing to take the hit on fuel mileage in trade for longevity, reliability and cost of repair if anything ever goes wrong.

Random side note: I racked up hundreds of thousands of miles on 1997-2000 Chevy 3500 vans with the Duramax. Averaged just under 30mpg towing an 8,000 lb trailer with fully-equipped cargo racks and tools inside the vans. On the rare trips without a trailer, mpg was usually close to 25. They were the opposite of these new small-displacement turbo cars. Obviously designed to be loaded up and driven, but not very efficient with minimal load. Loved those vans.

That's better fuel economy than my 3.4L V6 2002 4WD extended cab manual transmission Tacoma.

It's about the same mileage I get with my 07 Canyon with the 2.8l and 5 speed manual.
