Both completed and on-going. Do note that all of this is just my own opinion, and in no way am I trying to persuade you not to read the ones that I rated lowly. Everyone has their own taste, and opinions. Won't rate the ones I haven't read/still reading. 

Rating:
☆☆☆☆☆ - A great novel that's worth reading, not a waste of your time. Great plot and characters. Will definitely reread. 

☆☆☆☆ - A good novel, with questionable but still great characters and with good plot, might reread again. 

☆☆☆ - Mediocre novel. Good for those with low standards and just wanted to increase their reading count. Okay plot and not well-developed characters. Not gonna reread again. 

☆☆ - Passable. Just meh, close to shitty, with near to no redeemable qualities. Either the way the characters were written or the plot itself. Will not reread.

☆ - Absolutely not worth your time. Will never touch again. 

ーーーー
TL:
★★★★★ ー Great translation, close to none grammatical errors. 

★★★★ ー  Good translation, with bits of errors here and there but would still not destroy the novel somehow. 

★★★ ー Passable. Resembling edited MTL with questionable translation/grammar.

★★ - ★ ー English resembled MTL. Just copy paste, ★★ will be slightly edited but still copy pasted MTL overall, and ★ is just copy pasted.
