I prefer OJs for a number of reasons (no surprise):
- I prefer actual photo over cartoon
- Interesting HOF selection (29 HOFers with far more poses to consider than T206) including Anson, Delahanty, Kelly, Wright, Rusie, and White to name a few. Their histories are every bit as interesting as the early 20th century players if you care to study them.
- Hard to beat the glimpse into early baseball history, from barehanded players to early catching gear.
- Cabinets to complement the small cards which give you an opportunity for a little color if you like that (mounts)
- Far more Leagues and Teams than T206 (I think "The Monster" is more appropriate for N172)
- Many ways to collect that can fit varying budgets
- OJs & GQs as separate sets, just like T206 should be split into separate sets (my opinion)
- OJ also has the prohibitively expensive rarities to dream about . . . Anson in Uniform (Wagner), McGreachery (Plank), and so on
While many cards are tough, many are very obtainable. We've seen some board members assembly pretty complete team sets in a rather short time for example.
