You cannot really compare what is best. What you must think is the most practical. Well I put it in this order by keeping in mind of the principle of extensive usage like a renewable energy that while you are using it, you are at the same time given a power source and double what you can do to produce results. So getting and using the TCredits first enables you to have used something like a renewable energy. While you are using TCredits in auctions, you are also earning another means to buy S-Builder or IAHBE. That is by accumulating MRPs. Then when you already duplicated yourself and earned enough to buy another TCredits, that's the time that you may subscribe to IAHBE.
