Either method in all honesty one is not easier than the other and things can go wrong with both. When I first started I only wanted to make castille but heeded all the advice to use a certain % hard oils, CP only, up to 20% CO etc. The result was that it just took me much longer to get around to making the soap I really like 100% OO castile which is what I make today. All the other little adventures, while I don't regret them, weren't really necessary.
So I would say make the soap you want to make right off the bat. Less materials to buy, less things to worry about. >5% coconut oil with olive oil and any level of superfat will produce a very nice soap. Go for it.
Also my personal tip is that a stick mixer isn't necessary, I have never used one and I've been making soap for 2yrs. If I have an oil that takes a while to trace I just mix in the lye with a whisk and then every 30mins or so give it a stir until it reaches trace. I use EVOO and no heat and it reaches medium trace in about 3hrs like this. No need to stand there stirring it, just do other things (sometimes I will even sit it in the sink with a lid, go out for a while and check it when I return. No hassle, very easy. Once it's thick like custard pour it into a mold and forget about it for a few days, pop it out when firm and cut.
Hot process will require you to be at home for the entire time because it's on the heat, so you need to watch it. It also takes a couple of hours but you have to be home. It will be thick like glue when you put it in the mold, so it's more difficult to deal with fully cooked and you will get a more textured bar as a result.
Make two batches, 1 cold process (1kg oil) makes about 10 bars and 1 hot process then decide for yourself which one you like the best. I switch between the two depending on my mood.
PS - I use my castile bars anytime after 2 weeks. The less cured soaps just won't last in the shower as long but I don't find much other difference apart from that.
