Hi welcome along to the forum and the hobby
Fishless Cycling or Fish In Cycling is not really a choice - just do Fishless, it means a bit of an unorthadox approach to people new to the hobby but it really works and no shops will ever tell you about it. You add in a small amount of household ammonia each day which simulates the harmful chemicals fish poo creates and it gets the tank into a stable situation for fish to be added - down side is it takes a few weeks to do it and means no fish in the tank for this period but for the long term life of the tank this is the best option.
Heres a good section on thsi forum that is not always that easy to find

Read through the Fishless Cycling article and also the Nitrogen Cycle which will help explain why we need to do the cycle.
Have you had a think about any fish for your tank yet?
A few good sites for you to look at are
seriouslyfish.com
planetcatfish.com
Both are great sites with good profiles.
One tip when you do start getting fish, try not to impulse buy and dont always trust shop assistants as you can sometimes end up with small fish that will grow into monsters. Avoid any fish that are silver and called sharks just skip them, bala sharks, iridescant sharks, blue sharks all are just problematic - some fish termed as sharks are okay though and most other silver fish are good as well lol but these fish always cause issues.
Hope thats helped
