How to tell them apart
らしい conveys a conjecture based on what you have heard, read, or seen, so it works when you are reporting or inferring from external evidence. っぽい attaches to a noun, adjective, or verb to say something has a distinctive characteristic or tendency, giving a -ish or -like feel. Swapping them is unnatural: 安っぽいソファ means cheapish, not apparently cheap, while 難しいらしい means I hear it is difficult, not difficult-ish.
- らしい Use らしい when you are conjecturing or reporting based on something you heard, read, or saw.
- っぽい Use っぽい when you want to say something has a characteristic or tendency, like -ish or -like.
