Which one was faster They both had the same engines and which one could carry more also between the DC6 and the regular Constellation which one was faster and which one could cary more. You can ask me about the ATR I let you know thanks.

The Super Connie seems to have been the faster of the 2 with a cruising speed normally in the range of 290-300 M.P.H.,whereas the DC-7C cruised at 255-260 M.P.H.
DC-7C had a max payload of 21,516 lbs (9,759 KGS),the Super Connie max was 18,300 lbs (8,300 KGS).
Connie Model 749 cruised at 327 M.P.H. with max payload of 16,300 lbs (7,395 KGS).Similar numbers for the DC-6A and B were 315 M.P.H. (both) and 28,188 lbs/12,785 KGS (A) and 24,565 lbs/11,142 KGS (B).

Judging by TWA and AA/UA timetables the DC-7 was faster on transcon nonstops.

FWIW I read where the DC7 cruised at 367 MPH and could do 405 MPH flat out. Of course that's official data...the actual in-service speeds were more than likely less.

In August 1957 the UA and AA DC-7 nonstop schedules between LAX and IDL were 7:45 eastbound and 8:35 westbound. TW had one 1049G each way, 8:22 EB and 9:34 WB, and two 1649s in 8:17 EB and 9:27 WB.

When transcon nonstops first started there was some sort of rule about needing another flight crew on domestic flights longer than 8 hrs (but Hawaii wasn't domestic then). So in 1954 TW scheduled a 7:55 eastbound nonstop (no westbound) and in Jan 1955 they claimed to fly eastbound in 7:15 and westbound in 7:55. And that's with 1049s, not 1049Gs.

Between IDL and Orly the August 1957 nonstop schedules were 11:25 EB 13:45 WB on a PA DC7C, 11:40 EB 14:10 WB on a TW 1649, and 13:50 EB 16:30 WB on a TW 1049G with a "fuel stop may be necessary" footnote. Forgot to check Air France.

From Flight, 10 June 55 p785:

Lockheeds claim that their new airliner [the 1649], powered by four 3,400 h.p. Wright Turbo-Compounds, will be capable of carrying 58 passengers for 6,500 miles at a cruising speed of over 350 m.p.h. and that it will fly from Paris to New York in nearly three hours less time than the DC-7C when carrying the same payload as its Douglas competitor.

Don't believe it, of course.
