Dull_Razer, I really appreciate the work that you (and everyone else here) have put into these boards to revive them! Great job! Since I don't really have a main, use a lot of characters (all but Peach, Jiggs, Sonic), and lurk a lot of boards, I guess I'll give you guys some input.
ROB's attributes:
+ROB has a better recovery (Impossible to gimp)
+ROB is heavier
+ROB is a better long-range camper because:
Toon Link has only one projectile that can reach the length of FD (strong-boomerang almost can), and it needs to be charged, while ROB has two (but one also needs to be charged to reach that far)
+ROB generally outranges TL on the ground with ftilt and dtilt.
+ROB is a better ledgestaller]
+Has an "item-projectile" that he can glidetoss
+Better dsmash
-Bad kill options aside from gimps (nair is good but it won't kill until 140's on a grounded opponent with average DI)
-Larger frame
-Runs slower
-WEAKSPOT BELOW HIMSELF
TL's advantages:
+Better mid-range camper/spacer (At this range all three projectiles work, which means he can do things like SH bomb pull->quickdraw, Bomb throw->quickdraw, Zair->Bomb SHDA, and he can utilize his boomerang.)
+Has a zair (outranges all of ROB's non-projectile moves when well-spaced)
+Can attack out of an airdodge (zair)
+Can ledgegrab out of an airdodge (zair)
+Bombs cannot be canceled out (only caught)
+He can do aerials with bombs using ZAC/iZAC
+He can bomb recover
+He can safe spike with bombs (especially useful against ROB since his recovery ususally doesn't sweetspot the ledge)
+He can f-smash with bombs
+He can usmash with bombs
+His dsmash CAN gimp ROB if he decides to charge a smash attack at low percentages beside the ledge (extremely situational)
+Excellent recovery which is hard to gimp due to having several options
+Can JC throw his bomb directly out of a dash (his slide looks really amazing, just not as far as ROB's)
+DESTROYS ROB's weakspot with better aerial movement, powerful Usmash and Uair, Utilt juggles, and bair combos.
+Hylian shield stops projectiles if he just stands there or crouches (except it doesn't cover his head or feet when standing, and only his head when crouching, so a well-spaced gyro or well-aimed laser can exploit this)
-Lighter
-Less range overall
-Slow and EXTREMELY punishable grab
-Bad throws overall
-Hard to land kill moves (usmash is hard to set up, although powerful, fsmash can be DI'd out, Dsmash kills at upwards of 150%, fair will really only kill when edgeguarding, uair is powerful but lags a lot if it misses)
Ratio: Between 45:55 and 55:45
What to watch out for, otherwise known as TL;DR: Zair, bombs and bomb mindgames, powerful Usmash, bair combos, midrange camping, quickdraw (hitbox comes out frame 2, fastest move TL has besides z-drop). You two both may have some troubles killing.
EDIT: Lol big wall of text
Here's a list of his AT's:
By Fox is Openly Deceptive
It's worth it to take a look at his AT's, as my "What to watch out for" really only covers the basics.
