Imo, if you're serious about your project (i.e. you want to start a biz, not just run a side project), then you want:

- .com domain name (buy also others, but you need the .com)

- name clearly understandable, possibly even by non-native speaker

- name without strange plays on words that you only understand

- name without any subtle replacement/elision of letters

- name that doesn't start with an article (e.g., the)

- name that you can pronounce very clearly

In short, any random person that you meet, should be able to get and remember your name and find the related .com domain.

The easiest way is usually to combine 2 words, or a word and a number.

In the 2 words case, your domain name will also be your product name, I assume. Don't try to write it in any strange way. Your name will be ProductName, or Product Name, available at productname.com. Any other attempt is a waste of your time, and everybody will misspell it.
