There are negatives and positives to WOTR, Solasta and BG3. Peoples perspectives are going to vary based on personal preferences.
WOTR Pros - Party of 6. - 3.75 System More Verstility than 5E - Good/Evil Choices In general feel more relivent to the game itself. - Mounts - RTwp Option for those that want it. (Don't care myself) - Larger Equipment Options - Random Encounters
Cons - 3.75 System can be difficult on begginers / Lacks Balance of 5e. - Mythic Levels and extra add-ons can feel make you feel like your getting over powered. - Difficulty late game can feel very choice limiting at higher difficulty levels.
Solasta Pros - Character Creation Screen has far more initial options - Sticks to all the 5e rules. - Full party interaction. - Stat rolling option.
Cons - Limit of 7 classes from 5e. - Party doesnt really give you the individual feel of each character mattering as much it feels less story driven with lack of companions. - Not core with races.
BG3 Pros - Higher system graphics makes the game look more asthetic. - Combat does seem to be more fluid in current state. - Immersive dialogue options. - Target to Include all core options. - Multi-Player Feature.
Cons - Lack of ability to diversify the appearance of your character//Initial character design in general is super limiting. - Choices feel non-Impactful - A lot of homebrew rules. - No Random Encounter Options.
Im sure there are more things could go on there but those are the more stand out things.
I would add to WOTR pros:
Lots of playable companions. A night/day system + weather Great UI Super portraits Part of 3.75 system but still: TONS of classes/kits options.
WOTR cons: Not of fan of the color palette, better than Kingmaker but still a bit too cartoony.
add to BG3 Pros: Really like the spell icons; This is probably the ONLY thing that reminds of BG2??
add to BG3 cons: CRAP console like UI with stupid chain mechanic. Cinematic dialogues for EVERYTHING slows the game to a crawl. AGAIN, feels a bit too cartoony/vibrant! Whats with RPGs being like this these days?? Give me rated R dark and gritty!!!! Diablo 2 remake is finally a game thats getting there!? Maybe?!
