Here's the tier list for the characters.
S-"Soma" Tier
By far and away the best character in the game. He can do everything and do it effectively and even better that the characters that are supposed to specialize in that area (lol Charlotte.) Has has Valmingway which he can boost for crazy damage with Miser Rings and souls, he has the best and most useful spells, yorick and Medusa Head give him the best mobility and shortcuts, Oxectuiner is stupid good and gives him a barrier that blocks so much stuff and can add to Valmingway's damage. Anything that resists Valmingway gets wrecked by Warg or Fish Head or Soma can just boost his attack and strength to break through enemies that resist slash. Soma just overshadows everyone by miles.
A-
Alucard-
He's Soma light. Almost everything he has Soma doesn't is garbage except that he can move while using Yatsuna +1 and mist is decent. That fact that he's still second best show how stupid Valmingway and Yastuna +1 are.
Shanoa-Shanoa is limited but Globus and Acerbatus are really powerful and help secure this spot. Her other spells are mediocre and her weapons are meh. Download chapter 8 and 9 if you plan to use her because she's pretty lousy without those spells.
Richter-The most mobile and damaging Belmont. His martial arts are all good except his uppercut, his whip has great range and he's tied with Simon for highest base strength. He can combo whip into spin kick into tackle and destroy pretty much any common enemy in your way. His has a few flaws like being the slowest subweapon thrower (you can use subweapons in the air or backdash cancel to remedy this) and he has the biggest hitbox tied with Alucard even through it doesn't look like it. The only reason Shanoa and Alucard are above him is that he can't destroy bosses in seconds like they can.
B-
Julius- A pretty good character. His 8 way whip is good for hitting enemies and he doesn't need an Axe as badly as the other Belmonts. His Akuma teleport is the best dodge move in the game and can be canceled into attacks. he doesn't have any other martial arts other than uppercut through and has the second fastest Subweapon throw. That's pretty much it through, he's balanced but not broken like the other 4.
Simon- Simon is simple but effective. He has the fastest subweapon throw and whip with having almost no startup or recovery . And his whip has really great range for his small hitbox. That's it however as his fireball is pretty much useless and he doesn't have any other special skills or martial arts.
Jonathan.-The worst whipper. Slowest, weakest and has the worst range. Third slowest subweapon throwing speed, most of his unique subweapons suck and the ones that were useful are mostly obsolete by the retro weapons or were ruined by the DLC enemies and bosses being resistant to slash. His danger knee is pretty good at least and he can "sonic jump."
