Which is lighter, the Saucony Guide 15 or the Guide 16?

Neither by a meaningful margin. Both weigh about 9.5 oz in a men's US 9.

Do the Saucony Guide 15 and Guide 16 come in the same widths?

Yes. Both run in D, 2E for men's sizes, so a width that fit in the Guide 15 carries over to the Guide 16.

How do the stack heights compare?

35 mm heel and 27 mm forefoot on the Saucony Guide 15, against 35 mm and 27 mm on the Guide 16. Same platform under both.

Is the Guide 16 still the newest Guide?

No. The Guide 17 replaced it in 2024, so the Guide 16 now sells as an older model and usually below its $140 list price.

Faithful successor

THE SHORT ANSWER

Whichever your size still exists in. Both the Guide 15 and Guide 16 are down to thinning size runs, so fit and the ride changes below matter more than nominal list price.
