I've been investing in ASX shares for many years now. Over my investing journey, I've had the misfortune of making a few costly stock-picking mistakes. But I have also been incredibly lucky to invest in some truly lucrative ASX shares.

Unfortunately for all of you patriots out there, my absolute best performers in recent years have not been ASX shares, but American stocks like Netflix, Duolingo, and Meta Platforms.

But I still do have some notable winners amongst my local holdings. So today, I'm going to discuss three of my best ASX shares and reveal which one I would buy more of today.

Three of my best ASX shares

First, we have packaging stock Pact Group Holdings Ltd (ASX: PGH). I bought Pact shares many years ago when they were trading at what was then a relatively cheap price. I bought a big chunk of Pact and, fortunately, sold out when the company hit a multi-year high in late 2021. Over just two years, I managed to bank a 150% gain.

I was very fortunate to sell out when I did, as Pact has subsequently run into some structural issues, and its shares have fallen below my buying point. Even so, this company remains one of my best ASX investments ever.

Wesfarmers Ltd (ASX: WES) is another ASX share that has done very well for me. I picked up Wesfarmers stock back in mid-2022 for around $40 a pop. Today, those shares are worth just under $76 each, meaning I've enjoyed a return of around 85% (even more when dividends are included).

Unfortunately, I didn't buy as many shares as I would have liked back then, and I have regretted it ever since. However, I view the Wesfarmers share price as a little lofty today. It's not so high as to prompt me to sell out, but I'm not comfortable adding any more capital to this position right now.

Last but not least

Finally, we have the VanEck Morningstar Wide Moat ETF (ASX: MOAT). This exchange-traded fund (ETF) has been in my portfolio for many years and has more than doubled since I first bought it for just over $60 a unit back in 2018.

MOAT holds a portfolio of US stocks that all display characteristics of possessing a wide economic moat. A 'moat' is the Warren Buffett term that describes an intrinsic competitive advantage that a company can possess. This typically comes in the form of a strong, powerful brand, low-cost advantage, or having a product or service that consumers find difficult to avoid.

Given this ETF's diversified portfolio and uncharacteristically muted performance over the past 12 months, this is the one best performer in my ASX share portfolio that I would happily add to in today's market.
