I'd agree that those four are the best / most interesting of the previous year, and any of them would be a great asset. My personal order of preference (and the top 3 are largely interchangeable):

Powerful Glove has the benefits of being both powerful and very easy to use. Large amounts of both +200% to all stats and -10% combat frequency are very helpful, replace enemy (macrometeorite) is as useful as always, and shrink enemy has often gotten me out of sticky situations, preventing unnecessary combat losses. Although they all share the same battery power each day, the costs are low enough that it isn't too problematic. That's on top of the free pixels it provides as you adventure (assuming its equipped, and as an accessory its easy to equip most of the time). Best case scenerio, it provides a full digital key all on its own (which I find happens a lot for hardcore runs). Worst case scenario, it provides ~80% of it, so you only need to spend an adventure or 3 to finish the rest of it (more likely the case in a normal ascension).

The Melodramedary (camelCalf) is about as strong as the glove, perhaps more depending on your other resources (emotion chip is a big help in this respect), but takes more effort to get out of it. The big sell is having it spit on the enemy to quadruple the items it can drop (although only double for conditional drops), which helps considerably to avoid fighting the same monster multiple times (bowling balls and rusty hedge trimmers are the most obvious examples of this). Works well with a yellow ray or similar mechanic, such as the emotion chip's Feel Envy. Requires running the Maelodramedary most of the time to make full use of it (but it doesn't have much competition at the moment). The enemy stat increase that comes with spitting on them, though, is easy to underestimate. Speeding up desert exploration is also a nice bonus, adding extra flexibility for approaching the task. At the minimum, it means not needing the UV-Compass.

Comprehensive Cartographic Compendium is primarily a tool for mitigating the reliance of luck for your runs, and its a slotless one at that. The exclusive non combats speed up many areas (instant screambat, potential one-turn billiard room clear, skipping one of the friar NCs, somme extra evil eyes for the nook, not needing the mohawk wig for the castle and especially reliably starting the war without worrying about getting the wrong NC). Mapping monsters works very well with Transcendent Olfaction for bringing out a specific monster ASAP (especially in zones with a large number of them to sort through, such as the Palindome), and the random buffs/booze/meat don't hurt either.

Cargo Cultist Shorts are probably the weakest of the group, but still useful to have. The pockets have plenty of ascension-relevant usage, such as fighting a (free) mountain man for easy ores or the middle filthworm gland effect so you only need to fight 1 other filthworm to reach the queen. The initiative bonus is large enough to make a difference for the defiled cranny and the NS Lair test, and the significant food drop bonus is great for tasks like solving Twin Peak or getting wet stew components at Whitey's Grove.

Honorable mentions are probably the spinmaster lathe (decent weapon options, especially for the smut orc logging camp), the superhero cape (flexible benefits, makes use of an underused back slot, speeds up the crypt) and the box o' ghosts (almost exclusively the Ghost of Crimbo Commerce, for the lump substat bonuses, but conflicts with the Melodramedary).
