OK, I want to start out by saying that I haven't yet seen the newest Riddick movie (I have seen all the others though) so anyone who has seen it, can you please keep posts as spoiler free as possible. Thank you.
Now that being said, this could honestly go either way.
-Riddick(while having fewer weapons and equipment) knows his environment, can see in the dark, has low-tier super human feats ( strength, agility,stamina,reflexes, and endurance),knows little to no fear, can think on his feet, and is extremely resourceful in combat.
-Predator (a fully blooded warrior, not the unbloodeds we see in most movies)has advanced technology, hunted across countless hostile alien environments, has at least a hundred + years of experience in fighting, above human feats in strength, agility, stamina, reflexes, and endurance), knows little to no fear, fallow a hunters code, and are extremely resourceful in combat.
The equipment of a predator is fairly standard throughout the ranks of a the predator hirarchy; however, the higher up you are the better/ higher grade the equipment is (for example ranging from a simple mask(low rank) to fully automated hunting systems in one helmet(highest rank).
The equipment is:
-Cloaking Device: Light-bending adaptive camouflage allowing Predators a form of invisibility, or at least translucence. The invisibility effect has been known to be shorted out through contact with water, or if the arm gauntlet is damaged.
-Bio-Mask: The Predator's mask contains systems to enhance its vision and provide additional vision modes in other electromagnetic spectra. It also grants access to Vocal Mimicry and the Language Translator, and records anything the Predator sees so that it may be reviewed at a later date.
-Wrist Gauntlet: Includes the Predator's Sat-Com and sometimes a Plasma Bolt or Power Glove. Also incorporates touch-pad technology to control a Predator's Cloaking Device, Self-Destruct Device, and even remotely pilot Predator vessels.
-Medi-Kit: Predator hunters carry field medical equipment including solvents capable of cauterizing and healing Predator wounds and various serums and other medical devices.
-Armor:The armor comes normally in light (allows for a greater range of maneuverability) or heavy( greater protection). Light armor is generally preferred for normal hunts, where as heavy armor is used in tribal warfare / blooding ritual hunts.
The weapons:
-Wrist Blades: Razor-sharp serrated blades worn on a wrist gauntlet for close combat.
-Scimitar: Essentially an enlarged Wrist Blade worn on the forearm / held in the hand.
-Plasma Caster: A ranged weapon capable of directing plasma bolts at distant targets. Aimed through the Predator's Bio-Mask.
-Plasma Cannon: A hand-held version of the Plasma Caster.
-Spear Gun: A projectile weapon that fires small metal spears, comparable to a traditional firearm or crossbow.
-Combi-Stick: A retractable spear that can be used either in hand-to-hand combat or as a thrown weapon.
-Net Launcher: A handheld device capable of firing a wire net with enough force to pin a target to a wall. The net also features an automatic tightening mechanism designed to cause grievous wounds to the enclosed target.
-Smart-Disc: A self-guiding discus-like cutting device.
-Shuriken: Similar to the Smart-Disc, except considerably larger and fitted with several fan-like blades.
-Glaive: Similar to the Combi-Stick, this combat staff is fitted with a sizeable blade at each end.
-Maul: A heavy bladed weapon comparable to a police officer's nightstick.
-Whip: A segmented bull whip capable of slicing targets in half with enough force.
-Mines: Predators utilize a variety of mines with varying detonation effects in their hunts.
