I have been in the hobby for 3.5 years. Honestly only the last 6 - 8 months have I been able to not only keep acros alive but growing. I struggled for a long time with my nitrate to phosphate ratio, nitrates 20+ and phosphates undetectable. Once I got those in balance my coralline algae exploded in my tank, I mean exploded, that is when I was really able to keep acros. Start with a cheap plating monti, they are tough and they will also explode in growth when your tank is mature enough and you can keep water parameters very stable. If you are looking for a branching coral that is easy to keep both branching psammocora and branching cyphastrea have a kind of acro appearance and are hardy. When conditions are right you will really notice them growing too.
