I can give you an outsider's perspective if you like. Granted, I don't bet baseball so it may even hold less interest for you.
Honestly, from a reader's perspective, I like to see the record and the units. Because one without the other can only tell you part of the story. You might have a great W/L record except, you play favorite MLs a lot and so you're really not making many units, or you're even losing money overall. Conversely, you may play a ton of ML dogs and be at less than 50% W/L, but be up units.
This is one reason I haven't posted a record in years. I'm lazy. I don't want to list it all out, by sport, in total. I don't do this for a living so it's not like I have that number at hand all the time.
The other thing that can be hard to tell is if you don't post it for everything you do. I used to keep a football record and post it, but then I noticed when other sports started and I played them occasionally, or when I bet 2nd halves and didn't post 'em, I ran into that area where my posted record was accurate, but not accurate if you know what I mean.
For example, in the NCAA tourney, my goal was 20 units. I hit that (thank you, Gambling Gods), but a few times during that tourney, I played some bulls**t NBA games and lost. So while I technically hit my 20 unit goal, for the time-span I specified, for a while I also technically didn't (e.g., 20 units profit on NCAA - 4 Units NBA = 16 units net profit, not 20 as the goal specified).
But what was I going to do, my NCAA record was accurate, I was up 20 units for the tourney, but I was also down in NBA units in unposted NBA bets, so you could argue that my record was inaccurate.
Bottom line, that's mostly why I just say screw it and will only do records for set events (the tourney, or I'll probably do it for the NHL playoffs if I can catch up informationally by the time they start), but for entire seasons, I choose not to.
But as a reader, it's most educational if it's both. Though that's not what makes me choose to follow a poster's thoughts.
Hope that helps.
