Just be honest with yourself and say that you subjectively like it better that way, as it grew on you.
There is nothing wrong with that reasoning. Also, there will never be a language which is perfect in every conceivable way, this is such a minor difference that if someone chooses a language over this alone, they are not being reasonable.
1. After 5 minutes, you know what sizes they are, and don't need reminding.
2. Easier to touch type.
3. They're just aesthetically more pleasing to the eye.
4. The names aren't really different, they follow the most-used (by far) sizes on C.
5. It's easier to say and hear them. I can say "int" when talking code with someone, instead of "eye-thirty-two".
6. I'm guessing it may be easier for a visually impaired coder with a screen reader.
