Hello again, r/Vocaloid! Sorry if the title is long on the post, so I'm putting the discussion question here as well.

What is/are your favorite things(s) about your favorite Vocal Synth(s)? (What you like about them, favorite songs, etc.)
What are your least favorite thing/something you wish they had/had more of? 

For me personally, my favorite female vocaloid is Gumi while my favorite male vocal synth is probably have to be Kaito. Gumi and Kaito's voices/voicebanks can be really smooth yet powerful in their own way if they tuned properly. I also really like Gumi's design and we actually share really close birthdays (her anniversary is on June 26th while my birthday is on the 30th.) 

Some of my favorite songs featuring Gumi: Mozaik Role by Deco*27, Amanojaku by 164, Eye Examination by 40mp, Copycat by CircusP, Muzzle of Nemesis by Mothy, Echo by CrusherP, 1,2 Fanclub by MikitoP (with Rin), Water the Roses by Flavor Foley, or anything produced by KIRA, etc. 

Some of My Favorite Kaito Songs: Electric Weekend Zone by Flavor Foley and CircusP, Snowman or AttaKaito by Halyosy, Thousand Year Solo by YanagiP, Judas by Sukoyaka Daiseidou, Judgement of Corruption by Mothy, 1/4 by CircusP, Cantarella or Cresent Moon by KuroWhiteFlame, Cendrillion, On The Rocks, Shanti or Literary by Wotaku, etc. 

(There's probably more I could put but this is already long *sob*)

I'm hoping for more merch (especially the lack of Gumi merch is sad)for them in the future as well as more concerts.

What about you guys?
