IDK, my UTAU vocals were more forced(?), stronger and sometimes little talk-like sounding (that was probably because I didn't use BGM guide until 2016) but now?!?!???
I use nowadays Finnish BGM that is made by KLAD sempai almost everything. It's so good, easy to follow and melodic plus no over long waiting time until next recording when using auto 2 settings in OREMO ;3;
