I love that it's integrated with my gsuite account, so can access documents from anywhere without having an internet connection! The formatting isn't perfect yet- there are some inconsistencies in how italics work or where lists get indented etc., but this has been improving over time as they fix bugs/add features (I believe).
It does have great potential - if you're looking into using google drive more often then give preview marks down your first choice of tool since all files will be synced across devices automatically by default now too!! So much easier than opening each file individually online when not at home ;) Use Google Drive frequently enough though before jumping onboard fully because its quite expensive compared to other products out here like cloud9 which offers similar services; however their pricing model requires monthly payments rather tha just one payment once per year unlike Googles service plan :) Great product overall even after being around longer still getting better.
