Honestly IMHO it's not really fair to compare the two... They are very, very different programs as Charles pointed out... One is a rhinestone program HotFix and one has more options... DAS
That said... Hands down for me the better prduct for rhinestones is HotFix if you are looking at it for rhinestones which one can assume as that is all HotFix does... There is a huge price difference between HotFix and DAS too so that has to have some consideration...
Now there is a but because you also asked about ease of learning and using... This is a very gray area...
If a product cost three times as much but was easier to learn and use REALLY... Then no question that extra expense could be worth it...
So.... HotFix has a live demo you can actually use for a bit and see what you think....
Request a Demo
The drawback to that is you are on your own... There is very little info about how to actually use the product and this is where most programs let us down....
Now to the credit of DAS they have some tutorial content on their website but it's so very general it's of little real use but it's something.... They also claim to have this great member resource of video tutorials you get access to once you get their software... Sadly thought it's really pie in the sky... If I can't see what tutorial information is available before I purchase then it makes it real hard to make a purchase...
My best advice on rhinestone software it's so very simple... First try a real demo if it's available... Then you can get a feel for the software...
Now here is the real trick that will thin your selections quickly... Select 3-4 logos... Varying degrees of difficulty... Then ask the software vendor for an existing demonstration they have that is similar to these 3-4 logos... And if they don't have a video demonstration already then ask for a live demonstration... You will find very quickly either they simply won't do these demonstrations for you... Or they will do the demonstrations and you will soon realize good rhinestone design is not "easy"... There is actually work involved and know how required and you may not be ready to make that investment in time and money....
Get those demonstrations though before hand... Your logos... Not theirs!!!! That will tell you what you need to know in short order for sure!!!
