Jim is right about this one. However, there was a huge gap
between the RTTY world and the PSK world and it wasn't the
technical differences in the modes.
On field day you expect to find all levels of experience, from
the seasoned contest op to someone using a radio for the first
time in a GOTA station.
The RTTY stations I saw were all acting like experienced contest
ops, spread out with good space between the signals. To avoid
QRMing each other, callers would take turns. A typical QSO would go:
CQ FD N4XX N4XX
N4XX DE K6EI K6EI KN
K6EI 3A SFL 3A SFL K6EI
N4XX 11A SCV 11A SCV DE K6EI
K6EI TU QRZ N4XX
I was using K6EI and the N4XX call is made up. My transmissions
above were the macros I was using. I had a bunch of unnecessary
DEs and KNs, but the macros were set up for the PSK world.
The PSK world was quite different. Lots of people jumped in to
call CQ on top of ongoing QSOs. There were pileups everywhere.
The exchanges were also quite different. Some of the CQers
expected to receive the exchange before sending theirs. The
icing on the cake was one station which sent its exchange (not
quoting exactly, but recreating from a vague memory):
K6EI One Alpha South Florida One Alpha South Florida de N4XX
Needless to say, the rate with the RTTY stations was a lot
higher. However, most of the activity was on PSK. We spent less
that 2 hours on RTTY and 22 on PSK. (I had help from several
other operators who wanted to learn digital operations.)

of it to other modes
of digital modulation?
No, it's a different question. In the context of Field Day,
effectiveness is defined by the number of QSOs in the log, per
hour. And, for QRP battery, the 5X power multiplier.
