As far as sketching the floorplan: Pencil and paper is the best for me. I have tried Ipad + Total, ... Haven't tried ClickForms. The problem is that you have to piece everything together perfectly from scratch with those IPads - this wall 20'10" followed by that wall 4'10", out 18" chimney, across 3'6", back 18", then another 5'2", then right corner 15'8", obstruction - maybe 6'4", another 10'4", and so on until you get to the point were the lines should match and they don't and then you have to backtrack to figure out where you went wrong. Not nice. Scratchpad - I first do a rough sketch of the exterior and then go around and write down all measurements. I add up front widths and back widths to make sure they match and then side widths. Then I go inside, and write a rough layout of the interior based on the exterior. Try to zap the laser from one end of a far wall through to another front to back, side to side - if I have the openings to allow that, otherwise to the walls. Take down the exterior and interior wall thickness - as well as the one to the interior vs garage. Then I break out most rooms, especially complex ones, to separate sheets and go in and measure them, with a lot of attention to hallways. Pictures for everything every angle for reference. Make sure to measure depth of countertops. Also forgot to mention outside --- get the offsets for windows and doors. Get back to the office, bring up Chief Architect's Home Designer Pro and do a rough layout of each floor then click on the walls and type in the measurements - they all adjust automatically. I can immediately reconcile interior and exterior measurements. IF I made a mistake, which happens, I have long since learned how to make a few back-up measurements to reconcile any such problems - especially if I have those photos to reference.
Very flexible, very accurate. And, I can do those very difficult 100+ year old San Francisco Victorian triplexes.
But, I would also keep track of Matterport's progress. I have yet to see any Victorian triplexes they have done. But I'm guessing the stitching for these must take a long time (2 days?).
As for the other data, Total works pretty good. It saves some time, if everything is set up correctly. But paper and pencil is more secure ... for what it is worth.
