it would be like everyone has their own favourite word(s) for certain meanings...be it grammarical styles , or personlising of styles, or personality thing(!), or some like flowery words others just consider simple words as suffice. Suffice is like 'enough' but has different uses, like you will get boring or show limited vocab (hearies only) when repeat same words in letters or essays, which is why i use thesuraus ALOT....and even at that i still had to be careful to know what words are used for tricky tricky descriptions of thoughts or ideas
Travis addicted is fine, is used for 'fun side' but serious addiction some might use obsession then again, obsession can be used in a fun way too, really up to you. Sorry I got 'teacher-like' just helping but then I have to respect your way too. OK cheers
