You can use E6, ProTee, TGC, FSX. All are very accurate. One may suit your eye more than the others. Each software is unique so it's hard to pick. Both JNPG and TGC are good options because of quality and price. TGC has a rediculous amount of amazing courses and great graphics. JNPG has great features designed for the simulator world. There's no wrong answer. I'd focus on JNPG or TGC or both.
